#This cloudy-day black silicon solar cell can hit a record 22.1%efficiency When most people think of solar power,
theye usually thinking of warmer climates with lots of sun . Despite all the huge advances solar has made in recent years,
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.
Much of solar research has worked to directly convert infrared light to electricity, but such technologies change the transistor design,
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,
The overall costs of solar power lie much more in installation, maintenance, and land use costs than in the panels themselves;
but could still improve the affordability of solar power. Infrared radiation accounts for an enormous amount of the energy in direct sunlight,
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.
Plenty of raw energy is falling on highly clouded days, but the distribution of that energy through the spectrum is different,
and harder for modern solar panels to turn into power. Infrared radiation moves through and overcast sky quite well
but none is so direct as solar power. Energy will be one of the defining issues of the next few decades,
Wind turbines, especially offshore, could also benefit: the advantages of self healing materials far out to sea is clear. asically, any industry

Researchers say that this could be useful in the creation of rust-free solar panels that capture the sun energy
Nanowires are extremely thin nanocrystal threads used in the development of new electronic components like transistors and solar cells.
#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.
"The fuel was created by Audi's project partner Global Bioenergies, in France. In late 2014, Global Bioenergies started up the fermentation unit for a pilot program to produce gaseous isobutane from renewable biomass sugars such as corn-derived glucose.
Gaseous isobutane is a sort of raw material for the petrochemical industry that can then be refined into a variety of plastics, fuels and other applications.
"says Global Bioenergies CEO Marc Delcourt.""It is the first time that we have produced real gasoline from plants."
"says Rick Bockrath, vice president for chemical engineering at Global Bioenergies.""It's basically how we're moving away from an oil-based economy towards something that has a renewable, sustainable future to it."
"Audi and Global Bioenergies hope to tweak the production process in the future so that biomass is required no longer

"We have demonstrated simultaneously reversible storage of both solar energy and electrons in the cell,"says lead author of the paper Dong Liu."
"Release of the stored electrons under dark conditions continues solar energy storage, thus allowing for continuous storage around the clock."
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.

About three-fifths of those Hawaiian solar systems use microinverters from Enphase, the company that leads the market for DC-to-AC devices that sit at the solar panels themselves, rather than in one big box next to the power meter.
Third-party solar provider Solarcity, for example, has worked with HECO and Department of energy researchers to show that smart inverter technologies can allow more solar per circuit--an important concession for HECO,
which solar energy still depends. In addition, Asian rivals have made inroads into SMA's markets, putting pressure on equipment prices and profit margins.
Researchers Tout Solar panels Made With erovskitemineral A new generation of solar panels made from a mineral called perovskite has the potential to convert solar energy into household electricity more cheaply than ever before, according to a study from Britain Exeter University.
That means that CAISO is operating the grid, this month, at net load (that is the system demand less solar and wind generation) more than five years ahead of forecast.
California needs more energy storage to match the duck curve Experiencing this net load years ahead of the CAISO forecast has placed not the California grid in crisis. The state's grid has sufficient flexibility today to accommodate the rapid rise of solar power,

#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.

and storing solar energy into hydrogen. Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems.
To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen,
the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize.
EPFL scientists have developed now a simple unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost.
The work is published in Nature Communications. Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies
However, harvesting usable amounts of solar energy requires large areas of solar panels, and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale
called ungsten diselenide Past studies have shown that this material has a great efficiency for converting solar energy directly into hydrogen fuel
which is much less expensive than a traditional solar panel. The thin film produced like this was tested
#Reshaping the solar spectrum to turn light to electricity Researchers find a way to use the infrared region of the sun's spectrum to make solar cells more efficient.
When it comes to installing solar cells, labor cost and the cost of the land to house them constitute the bulk of the expense.
The solar cells made often of silicon or cadmium telluride rarely cost more than 20 percent of the total cost.
Solar energy could be made cheaper if less land had to be purchased to accommodate solar panels, best achieved if each solar cell could be coaxed to generate more power.
A huge gain in this direction has now been made by a team of chemists at the University of California
Riverside that has found an ingenious way to make solar energy conversion more efficient.
