Quasiparticle is unreal
Polariton quasiparticle is useless
Skyrmion, magnon quasiparticles are useless
(Fig.1) The very old fictional exciton quasiparticle model represents an electron and a hole transiently excited by laser or solar light.
Quantum mechanics unable to deal with multi-electron atoms has to describe any physical phenomena of materials or molecules by using fictional quasiparticle models that can Not clarify true physical mechanism.
For example, when laser or solar light transiently excites an electron (and a hole left ) of material and molecules in LED and solar panel, quantum mechanics tries to explain this transiently-excited electron (+ a hole ) as a fictional exciton quasiparticle ( this-3rd-paragraph ) which quantum mechanical pseudo-particle-model is very old, unchanged, impractical, since it was created in 1931 ( this-p.6 ).
This-6th-paragraph says "An exciton is Not a true particle, but a (fictional) quasiparticle"
↑ Of course, these fictional quasiparticle models such as exciton with unreal effective masses expressed only as nonphysical math symbols (= a†, b†.. ) with No real particle shape nor mass ( this-p.3, this-p.5, this-p.3 ) are useless for any technologies such as LED and solar cells, which inconvenient fact is hidden by an incredible amount of overhyped fake news and misleadingly-colorful picture trying to make useless quasiparticle models appear to be useful, promising.
Technologies of the solar energy, cells, panels have been deadend with No more progress.
Energy efficiency of the commercially-endurable solar panels can Not exceed 20% despite 70 years of researches ( this-7~8th-paragraphs, almost No progress from 15% in 1957, this-p.3-lower ) due to the useless fictional quantum mechanical exciton quasiparticle model ( this-p.6-p.15 ).
Light-emitting diode (= LED ) and solar cells are very old technology discovered before the (useless) quantum mechanics was created (= so quantum mechanics was irrelevant to discovery of LED and solar cells ).
↑ LED and solar cells were discovered accidentally or invented by trial-and-error-approach irrelevant to prediction of the useless quantum mechanics which unphysical (exciton) model just hampers LED from advancing now, contrary to hypes.
This-5th-paragraph says
"Nick accidentally created a red LED"
This-3rd-paragraph says
"To create different LED colors,... Trying out different compounds was a very slow trial-and-error process" ← Quantum mechanics was irrelevant.
This-2nd~4th-paragraphs say
"In 1954, the Bell laboratory in the United States accidentally discovered that silicon semiconductors doped with certain impurities "
↑ Despite the fact that the useless quantum mechanics was irrelevant to solar cells, the 2nd-last paragraph of this overhyped news says
"(fictional quantum mechanical quasiparticle) Exciton diffusion and transport are important processes in solar-cell devices, so understanding what limits these may (= just speculation, still unrealized ) well help the design of better materials"
The 2nd and last paragraphs of this overhyped news (1/29/2025) say
"Dark excitons are tiny pairs made up of one electron together with the hole it leaves behind when it is excited. They carry energy but cannot emit light"
"This means that this technique can be used in the future (= still unrealized now ) to specifically improve the quality and therefore also the efficiency of solar cells"
↑ This research paper's abstract says nothing about any practical use such as solar cells (= so exciton quasiparticle is useless for any technology ) contrary to the above overhyped fake news.
(Fig.2) Fictional exciton quasiparticle is too short-lived to be practical.
This fictional exciton quasiparticle representing an electron and a hole transiently excited by light has extremely-short lifetime of only 30 ns (= nanoseconds ).
↑ So this too-short-lived neutral fictional exciton quasiparticle is completely useless for any computers or storage memory devices (= which must store information for much longer time ), contrary to a lot of hypes.
The 1st paragraph of this overhyped news (2/10/2025) ( or this ) says
"A newly-discovered class of quasiparticles known as fractional excitons.... could have applications in quantum computing and sensing" ← untrue
↑ This research paper's abstract says nothing about any practical application such as (fictional) quantum computing nor sensing (= so useless research ), contrary to the above hyped news.
↑ This research (= p.2-Fig.1 & p.6 ) tried to associate some measured electric conductance (= called Hall effect caused by classical Lorentz magnetic force ) with fictional exciton quasiparticles having unreal fractional charges.
The last paragraph of this other hyped news (2/10/2025) on fictional exciton quasiparticle also says
"This research might (= just speculation, still useless ) possibly aid semiconductor development or quantum information science. The long-term goal is to better understand fundamental exciton behaviors, which might eventually influence applications in solar energy harvesting, or possibly, quantum computing."
↑ This research paper's abstract says nothing about any practical use such as (fictional) quantum information nor computing (= so exciton is useless ), contrary to the above hyped news.
The 2nd-last and last paragraphs of this other hyped news (3/19/2025) also say
"exciton particles (= fictional quasiparticle ) generated by illuminating the thin film with light"
"expected to contribute significantly to the development of quantum computing materials."
↑ This research paper's abstract says nothing about any practical use such as (fictional) quantum computing (= so useless exciton research ), contrary to the above hyped news.
↑ This research paper's p.8-methods shows this research just measured (macroscopic) magnetic susceptibility, optical properties, transmittance spectra by applying light or magnetic field to some material to imagine fictional exciton quasiparticles that have nothing to do with quantum computing.
The 7th and last paragraphs of this hyped news (6/12/2025) say
" This allows the excited state, which we call a triplet exciton (= fictional quasiparticle )"
"We expect that this development may (= just speculation, still useless ) contribute to solving global energy problems, as well as to expand into a wide range of fields such as cancer therapy."
(Fig.3) It is unlikely to discover new dreamlike material in solar cells or LED in the current macroscopic approach.
Researchers across the world have already investigated and known all the electromagnetic properties (such as response to light) of almost all materials suitable for solar cells and LED.
So revolutionary improvement or discovery of new dreamlike material in LED or solar cells will Not happen in the current conventional trial-and-error approach just measuring macroscopic electromagnetic properties of various materials without looking into the detailed ( real ) atomic mechanism (= due to fictional quantum mechanical exciton quasiparticle model ).
To break the deadlock in the current stalled technology, we have to look into and manipulate single atoms or molecules to design and build truly energy-efficient artificial photosynthesis nano-machines by using practical multi-probe atomic force microscopes whose development was hampered by the unphysical quantum mechanical model for 40 years.
The 2nd-last and last paragraphs of this hyped news on artificial photosynthesis (6/27/2025) say
"enabling the device to operate continuously for 140 hours" ← too short lifetime to be practical.
"The scalability of the artificial leaf into larger panels akin to photovoltaic modules signifies a decisive step toward (= still unrealized ) commercial deployment"
↑ This research paper ↓
p.1-abstract says even this latest artificial photosynthesis device has only 140 hour lifetime. ← too short lifetime
p.3-Fig.1 and p.8 shows this so-called artificial leaf was created by conventional macroscopic chemical procedure (= which cannot make true artificial molecular machines ), Not by manipulating single molecules.
p.7-Discussion-lower says "However, some challenges remain, such as (i) establishing an efficient conductive pathway..(ii) separating difficulty in the generated hydrogen and oxygen on the same side" ← still impractical.
The present deadend solar energy research continues making fruitless attempts to utilize organic solar cells (= impractical forever, this-1st~5th-paragraphs ) or pervoskite material for a long time.
The 3rd and last paragraph of this hyped news (8/6/2024) on vaguely says
"sought to control exciton/exciton annihilation... This perovskite material is a candidate for future (= still useless ) LED applications."
"The simplicity of the system suggests that this result should (= just speculation, still useless ) translate into other active materials in LEDs and solar cells"
Long-time researches have already showed this new allegedly-promising material Pervoskite is useless, easily-broken, and unsuitable for solar cells and LED. But researchers have continued to waste their time in these hopeless pervoskite researchers in vain ( this-6th-paragraph, this-middle-What is holding perovskite PV back ? ).
This-1st~2nd-paragraphs (6/12/2025) say
"Due to their high efficiency, perovskite solar panels have captured the attention of both the scientific community and the renewable energy industry. However, this material still has a number of fundamental problems, and it's not clear when it will enter the mainstream residential solar market. "
This-lower challenges to overcome (4/10/2025)
says
"The main issue with PSCs (= perovskite solar cells ) is their stability.... However, to compete with silicon, more research is needed to improve the stability of these devices." ← still useless despite long years of fruitless researches.
This overhyped news-middle-improving durability and performance (3/18/2025) also says
"A major limitation of perovskite solar cells is their long-term durability. Perovskite cells begin to deteriorate after just one year of use in contrast to silicon cells, which can last for 25–30 years."
"The University of Surrey.. enhanced the lifespan and stability of perovskite devices, maintaining high performance for more than two months (1,530 hours) " ← Even the latest research showed the only hope = Perovskite solar cell is easily broken in just 2 months, which is deadend, useless forever.
This research paper-p.2 (and p.6-left-lower ) tried to explain the solar cell by using fictional exciton quasiparticle model (= electron + hole ) expressed as nonphysical math symbols and one-pseudo-electron DFT with artificial-chosen potential (+ impractical AIMD ) which quantum mechanical pseudo-model is unable to predict any useful material, just hampering science.
The 1st and last paragraphs of this hyped news (6/26/2025) say
"Scientists.. have demonstrated a perovskite–organic tandem solar cell with a certified world-record power conversion efficiency of 26.4%"
"In the next phase of their research, the NUS team will focus on enhancing real-world operational stability" ← still stable perovskite organic solar cells are impossible despite longtime deadend researches.
↑ This research paper's p.38-Fig.34 says this perovskite-organic solar cell's performance (= photon conversion efficiency = PCE ) at maximum power point (= MPP = best condition ) drastically decreased and worsened just after 200 hours, which unstable perovskite solar cells are completely useless.
This-lower-current applications and future prospects-5th-paragraph (4/14/2025) says
"However, the development of stable and efficient blue PHOLEDs remains a challenge that researchers are actively working to overcome"
Unlike practical red and green PHOLED whose lifetime is long (= 20000 ~ 70000hr in LT 95% ), only the blue PHOLED is impractical with much shorter lifetime even in the latest research (= less than 1800hr in LT90 = the time to reach 90% of the initial luminance ).
↑ The 3rd and 3rd-last paragraphs of this overhyped news (5/23/2025) on blue PhOLED and fictional exciton quasiparticle says
"I can't say the problem is completely solved—of course it's not solved until it enters your display"
"This cuts the light-emitting burden of each layer in half, reducing the odds that two excitons (= fictional quasiparticle ) merge."
The last paragraph of another overhyped news (5/1/2025) also says
"With the technology still at an early stage of development, it will likely be some time before it appears in larger-screen devices such as OLED TVs – expect the rollout to take a couple more generations at least. There's also the question of the additional manufacturing costs it could introduce." ← still impractical blue PHOLED.
↑ No practical use of fictional exiton quasiparticles for LED nor solar cells, which inconvenient fact is hidden by an incredible amount of the overhyped misleading news.
