Insight into loss processes in perovskite solar cells enables efficiency impr...
1 Aug 2018 at 8:52am
In perovskite solar cells, charge carriers are mainly lost through recombination occurring at interface defect sites. In contrast, recombination at defect sites within the perovskite layer does not limit the performance of the solar cells at present. Teams from the University of Potsdam and the Helmholtz-Zentrum Berlin (HZB) were able to reach this interesting conclusion through extremely accurate quantitative measurements on 1 cm2 perovskite cells using photoluminescence.
Silicon-based, tandem photovoltaic modules can compete in solar market
30 Jul 2018 at 9:03am
The dominant existing solar technology -- silicon -- is more than 90 percent of the way to its theoretical efficiency limit. More efficient technologies will be more expensive. New research identifies the efficiency vs. cost target.
Technique to easily fabricate ceramic films used as OPV inter-layers developed
26 Jul 2018 at 1:20pm
Researchers developed a technique for coating Zinc related oxide (ZnOx, ZnOHx) simply by depositing the films in a solution process using the Metal Organic Decomposition method at ambient temperature and pressure without heating. They also demonstrated that their thin films produced by this technique were useful as buffer layers for OPV cells and that the films achieved a power conversion efficiency equivalent to that of ZnO thin films produced by conventional methods involving sintering.

Scientists report that a prototype semiconductor thin-film has performed even better than today's best solar cell materials at emitting light.
Europe may thrive on renewable energy despite unpredictable weather
26 Jul 2018 at 1:12pm
Researchers have shown how long-term weather patterns affect wind and solar renewable energy technologies across Europe. The work suggests that despite the unpredictable nature of wind and solar energy, the European power system can comfortably generate at least 35 percent of its electricity using these renewables alone without major impacts on prices or system stability.

How gold nanoparticles could improve solar energy storage
12 Jul 2018 at 8:45am
Star-shaped gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods - opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to researchers.
Conductive property of graphene, advancing promise of solar technology
10 Jul 2018 at 7:16am
Researchers have connected a graphene layer with two other atomic layers (molybdenum diselenide and tungsten disulfide) thereby extending the lifetime of excited electrons in graphene by several hundred times. The work may speed development of ultrathin and flexible solar cells with high efficiency.

A new design of rechargeable battery, created using salt, could lead the way for greener energy. Researchers have designed the novel energy store which allows for greater power while also lasting longer than conventional batteries.
New world record for direct solar water-splitting efficiency
5 Jul 2018 at 8:40am
An international team of researchers has now succeeded in raising the efficiency of producing hydrogen from direct solar water-splitting to a record 19 per cent. They did so by combining a tandem solar cell of III-V semiconductors with a catalyst of rhodium nanoparticles and a crystalline titanium dioxide coating.
Bacteria-powered solar cell converts light to energy, even under overcast skies
5 Jul 2018 at 5:42am
Researchers have found a cheap, sustainable way to build a solar cell using bacteria that convert light to energy. Their cell generated a current stronger than any previously recorded from such a device, and worked as efficiently in dim light as in bright light. This innovation could be a step toward wider adoption of solar power in places like British Columbia and parts of northern Europe where overcast skies are common.
Material could help windows both power your home and control its temperature
3 Jul 2018 at 8:28am
Environmentally friendly building trends have boosted the popularity of window coatings that keep heating and cooling costs down by blocking out unneeded parts of sunlight. They have also inspired scientists and engineers to create thin, see-through solar cells to turn windows into miniature electricity generators. Researchers have gone a step further and combined these two functions into one window-compatible material that could double the energy efficiency of an average household.
