Researchers at Finland’s Aalto University have achieved a record-breaking 22.1% efficiency for a nanostructured silicon, or black, solar cell. They accomplished this by overlaying a thin, passivating film on the nanostructures by a process known as atomic layer deposition, and by integrating all of the metal contacts on the cell’s back side. Perhaps the best part: Black solar cells work really well on cloudy days. “This is an advantage particularly in the north, where the sun shines from a low angle for a large part of the year,” said professor Hele Savin from Aalto University, who coordinated the study, in a statement. “We have demonstrated that in winter Helsinki, black cells generate considerably more electricity than traditional cells, even though both cells have identical efficiency values.” Using the aforementioned process, the team managed to beat their previous record by almost 4%, which is a stunning achievement. The new cells have a certified external quantum efficiency of 96% at 300nm wavelengths, which the team said shows that charged carrier surface recombination is no longer a problem — and that for the first time, the black silicon isn’t limiting energy conversion efficiency. And thanks to the inherent properties of black solar cells, they can capture solar radiation at low angles, generating more electricity over the full duration of a day as compared with traditional cells.

A road made of solar panel material is producing more energy than the creators expected. Engineers created a solar power bike path near Amsterdam that is over 200 feet long last year, and the road generated over 3,000kwh during the first six months, according to Al Jazeera, enough energy to power a house for a year. The company that created the road, SolaRoad, claims that means the road can produce 70kwh per square meter per year. The road is made of solar panels, glass, rubber and concrete. The road can either power street lamps or add power to the general grid. Over 150,000 cyclists have ridden on bike path without a problem since the project began. The path is made to be non-reflective and to prevent skidding. SolaRoad is still refining its materials to make them even more weather proof and efficient, and the company hopes to expand to larger areas in the future.
One of the fastest-growing areas of solar energy research is with materials called perovskites. These promising light harvesters could revolutionize the solar and electronics industries because they show potential to convert sunlight into electricity more efficiently and less expensively than today’s silicon-based semiconductors. These superefficient crystal structures have taken the scientific community by storm in the past few years because they can be processed very inexpensively and can be used in applications ranging from solar cells to light-emitting diodes (LEDs) found in phones and computer monitors. A new study published online April 30 in the journal Science by University of Washington and University of Oxford researchers demonstrates that perovskite materials, generally believed to be uniform in composition, actually contain flaws that can be engineered to improve solar devices even further.

Will China Be The First To Mine Lunar Energy?
In the United States, more than half of the energy we burn each year gets lost as heat instead of being put to use with most of the energy going out the exhaust pipe of a car or out the smokestack of a power plant.
Waste Heat to Power (WHP) creates electricity by heating a fluid at high pressure, then expanding the fluid through a turbine to power an electric generator.
Essentially, we're giving the solar panel a brain; the patented HEMOS chipset can be fitted in a typical junction of any solar panel. With it you can communicate directly with the panel and execute commands at the module level.
With constant innovations hitting the frontiers of solar power research, two recent studies provide a glimpse of new opportunities in way we are harnessing this source of energy.
If the shipping industry were a country, it would place sixth on the most carbon emission generating countries in the world. The good news is that solar in maritime transport is improving.
The process relies on heat and pressure to break down the long hydrogen, carbon and oxygen polymers that make up plastics. From there, these elements are recombined into the shorter hydrocarbon chains that can be effectively burned as diesel or gasoline.
