Inkjet printing process for kesterite solar cellsWed, 06 May 2015 11:15:24 EDT
A research team has developed an inkjet printing technology to produce kesterite thin film absorbers. Based on the inkjet-printed absorbers, solar cells with total area conversion efficiency of up to 6.4 percent have been achieved. Although this is lower than the efficiency records for this material class, the inkjet printing minimizes waste and has huge advantages for industrial production. First field-effect transistors on hybrid perovskites fabricated for first timeTue, 05 May 2015 10:24:39 EDT
Researchers have fabricated halide organic-inorganic hybrid perovskite field-effect transistors and measure their electrical characteristics at room temperature for the first time. Hybrid perovskites are a family of crystalline materials that hold great promise in the clean energy world. Saving sunshine for a rainy dayTue, 05 May 2015 09:19:51 EDT
The Sun is a huge source of energy. In just one hour planet Earth is hit by so much sunshine that humankind could cover its energy needs for an entire year if only we knew how to harvest and save it. But storing sunshine is not trivial. Now a student has researched his way to a breakthrough which may prove pivotal for technologies trying to capture the energy of the sun, and saving it for a rainy day. Engineering a better solar cell: Defects in popular perovskites pinpointedThu, 30 Apr 2015 15:50:53 EDT
A new study demonstrates that perovskite materials - superefficient crystal structures that have recently taken the scientific community by storm - contain flaws that can be engineered to improve solar cells and other devices even further. Artificial photosynthesis could help make fuels, plastics and medicineWed, 29 Apr 2015 10:48:11 EDT
The global industrial sector accounts for more than half of the total energy used every year. Now scientists are inventing a new artificial photosynthetic system that could one day reduce industry's dependence on fossil fuel-derived energy by powering part of the sector with solar energy and bacteria. The system converts light and carbon dioxide into building blocks for plastics, pharmaceuticals and fuels -- all without electricity.
