Iowa State University engineers have developed a next-generation perovskite solar cell that takes advantage of the promising electro-optical properties of perovskite materials. They’ve made the materials much more stable at high temperatures and demonstrated a consistent, clean way to fabricate them into solar cells. These would be important steps toward commercial production of new, low-cost, […]

Los Alamos National Laboratory researchers have developed new quantum dot solar cells that match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements relied on by most solar cells of this type. Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured […]

A Rensselaer Polytechnic Institute team of engineers, material scientists, and physicists have demonstrated how a new material – a lead-free chalcogenide perovskite – that hadn’t previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered. A widespread transition to solar energy will depend […]

DOE/National Renewable Energy Laboratory (NREL) scientists have fabricated a solar cell with an efficiency of nearly 50%. The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at […]

A Korea Advanced Institute of Science and Technology led international research team has developed a new type of solar cell that can both withstand environmental hazards and is 26.7% efficient in power conversion. Solar cells convert light into energy, but they can be inefficient and vulnerable to the environment, degrading with, ironically, too much light […]
