#Sharp Demonstrates Ultra-Efficient Solar cells The best solar cells convert less than one-third of the energy in sunlight into electricity
If it can be commercialized it would double the amount of power a solar cell can generate offering a way to make solar power far more economical.
when sunlight strikes a solar cell it produces some very high-energy electrons but within a few trillionths of a second those electrons shed most of their energy as waste heat.
The Sharp team found a way to extract these electrons before they give up that energy thereby increasing the voltage output of their prototype solar cell.
In theory solar cells that exploit this technique could reach efficiencies over 60 percent. The approach is one of several that could someday break open the solar industry
High-efficiency solar cells would lower the cost of installation which today is often more expensive than the cells themselves.
and figuring out how to make them with high precision (see Capturing More Light with a Single Solar cell and Nanocharging Solar).
which create a shortcut for high-energy electrons to move out of the solar cell. Another way to achieve ultra-high efficiencies now is by stacking up different kinds of solar cells (see Exotic Highly Efficient Solar cells May Soon Get Cheaper)
but doing so is very expensive. Meanwhile MIT researchers are studying the transient behavior of electrons in organic materials to find inexpensive ways to make ultra-efficient solar cells.
Each of the alternative approaches is at an early stage. James Dimmock the senior researchers who developed the new device at Sharp says he expects that his technique will initially be used to help boost the efficiency of conventional devices not to create new ones s
#Elon musk Needs a Very Big Factory for His New Solar technology The Tesla founder and private space entrepreneur Elon musk announced yesterday that Solar City,
And with typical bravado, he also said that the company plans to build a huge factory to produce Silevo high-efficiency solar panels,
it will also become a major manufacturer of solar panels, with by far the largest factory in the U s. The acquisition makes sense given that Silevo technology has the potential to reduce the cost of installing solar panels,
Solar City main business. But the decision to build a huge factory in the U s. seems daringspecially given the recent failures of other U s.-based solar manufacturers in the face of competition from Asia.
Silevo produces solar panels that are roughly 15 to 20 percent more efficient than conventional ones.
Silevo isn the only company to produce high-efficiency solar cells. A version made by Panasonic is just as efficient,
and Sunpower makes ones that are significantly more so (see ecord-Breaking Solar cell Points the Way the Cheaper Solar power.
if building huge factories to produce advanced solar panels can bring down costs, the market for solar panels could still grow exponentially l

#Gallium Phosphide Nanowires Significantly Increase Efficiency of Solar fuel Cells The solar cell made of gallium phosphide (Gap) generates clean fuel hydrogen gas from Water gap is a compound containing phosphide and gallium which also acts
the efficiency of the solar cell can be increased tenfold without using considerable amounts of costly material.
The electricity thus generated by the solar cell can be utilized to trigger chemical reactions. If these reactions produce fuel, then solar fuels would become a promising alternative for polluting fuels.
One efficient solution is to link a current silicon solar cell to a battery which is capable of splitting the liquid water;
when a huge flat surface is present as that utilized in Gap solar cells. The team resolved this issue by fabricating a network of small Gap nanowires
even at the extremely low power levels characteristic of tiny solar cells. Previous ultralow-power converters that used the same approach had efficiencies of only 40 or 50 percent.
Where most of its ultralow-power predecessors could use a solar cell to either charge a battery
Ups and downsthe circuit chief function is to regulate the voltages between the solar cell the battery,

#This cloudy-day black silicon solar cell can hit a record 22.1%efficiency When most people think of solar power,
or black, solar cell. They accomplished this by overlaying a thin, passivating film on the nanostructures by a process known as atomic layer deposition,
Black solar cells work really well on cloudy days. his is an advantage particularly in the north,
And thanks to the inherent properties of black solar cells, they can capture solar radiation at low angles,
and delivers vibrant color Light-emitting diodes (LEDS) are prevalent in everything from digital clocks to solar panels, traffic lights, electronic banners and signs, Christmas decorations,
and today most solar cells are based on silicon. In theory, the success with simple transistors implies that this material could also help continue advances in solar cells.
What most exciting here after graphene has saturated headline space for so long, is that there was only a few months needed to take this purely theoretical 2d substance from a computer simulation to practical, working transistors.
#New material combines photons for big solar energy gains An innovative new approach to solar energy from University of California Riverside could dramatically increase the amount of light available to contemporary solar panel designs.
Rather than widening the absorption spectrum of the solar panels themselves, this new study looked at taking currently inaccessible infrared light and turning it into visible light.
They hope that by directing this newly fabricated light onto conventional solar panels, the efficiency of solar power could be improved greatly, for an affordable price.
Infrared light currently passes straight through most silicon solar cell technologies representing a substantial inefficiency in generating electricity from sunlight.
and thus the manufacturing process for solar panels. Their impacts tend to be limited by cost concerns, more than anything else.
more importantly, it exists in a form that existing solar panels can absorb. By changing the incoming sunlight into silicon favorite for absorption,
the material could improve solar panel efficiency by as much as 30%.%And while the costs of the material itself are known not yet,
The resulting, lower-wavelength photons can move on to be absorbed by the transistors of the solar panel as normal,
and it is currently being missed by every solar panel outside of a research laboratory. In general, this sort of research into the manipulation of light could allow a wider rollout of solar power around the world.
and harder for modern solar panels to turn into power. Infrared radiation moves through and overcast sky quite well

#New record efficiency for black silicon solar cells Researchers at the University of Aalto, Finland have broken the efficiency record for black silicon solar cells a type of cell that can gather sunlight even from tight
allowing solar cells that use it to trap light even when it's coming from very low angles.
This could be a good way to increase the yield of solar cells throughout the day
as they don't need the antireflection coatings used by many other types of solar cells. The main issue that has stifled the progress of black silicon cells is something known as carrier recombination.
When a photon hits a silicon atom inside a solar cell, the excess energy frees up an electron that is later used to generate electricity.
#New energy cell can store up solar energy for release at night A photoelectrochemical cell (PEC) is a special type of solar cell that gathers the Sun's energy
While there's a healthy selection of compact solar panels to keep our mobile gadgets charged up light permitting the vast majority of these are either too small to be effective or too bulky for carting around.
while the actual solar panels are only 1. 5 mm thick. But Solar Paper has more going for it than just its form factor.
Both have been utilized individually by researchers to boost sunlight conversion to electrical current in solar cells, and to increase the efficacy of electrically-generated light.

#Chemists devise technology that could transform solar energy storage The materials in most of today's residential rooftop solar panels can store energy from the sun for only a few microseconds at a time.
A new technology developed by chemists at UCLA is capable of storing solar energy for up to several weeks-an advance that could change the way scientists think about designing solar cells.
To capture energy from sunlight, conventional rooftop solar cells use silicon, a fairly expensive material. There is currently a big push to make lower-cost solar cells using plastics
rather than silicon, but today plastic solar cells are relatively inefficient, in large part because the separated positive and negative electric charges often recombine before they can become electrical energy. odern plastic solar cells don have well-defined structures like plants do
