Gwangju Institute of Science and Technology scientists in South Korea have made ultra-thin photovoltaics flexible enough to wrap around the average pencil. The flexible solar cells could power wearable electronics like fitness trackers and smart glasses. The researchers report the results in the journal Applied Physics Letters, from AIP Publishing. Thin materials flex more easily […]

Swiss Federal Laboratories for Materials Science and Technology scientists at Empa have further boosted the energy conversion efficiency of flexible photovoltaic solar cells made of copper indium gallium (di)selenide (also known as CIGS) to a new world record of 18.7 percent. The same team achieved the previous record of 17.6 percent in June 2010 making […]
