Ecole Polytechnique Fédérale de Lausanne (EPFL) scientists have developed a solar-panel material that can cut down on perovskite based photovoltaic costs. Meanwhile the new cells achieve a competitive power conversion efficiency of 20.2%. Today, some of the most promising solar cells today use light-harvesting films made from perovskites – a group of materials that share […]






Researchers from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have published a new study that reveals the key market and system drivers for low-priced photovoltaic systems. The price of solar photovoltaic (PV) systems installed on homes and small businesses spans a wide range, so this study will benefit anyone interested in […]






Brown University researchers report a method for making perovskite cells larger while maintaining efficiency. Perovskite solar cells are cheaper to make than traditional silicon cells and their electricity conversion efficiency is improving rapidly. To be commercially viable, perovskite cells need to scale up from lab size. Researchers have reported efficiency in perovskite cells of higher […]






National Institute for Materials Science (NIMS) researchers in Japan have succeeded in producing highly reproducible and highly stable perovskite solar cells with a new low-temperature solution process. To date conventional perovskite solar cells produced by low-temperature solution processes have had problems in terms of stability and reproducibility, and details of their operational mechanism were difficult […]






University of Michigan (UM) researchers borrowing from the ancient Japanese art of paper cutting called kirigami have developed solar cells that are light weight and track the sun. Solar cells capture up to 40 percent more energy when they can track the sun across the sky, but conventional, motorized trackers are too heavy and bulky […]
