Australian engineers at the University of New South Wales (UNSW) have edged closer to the theoretical limits of sunlight to electricity conversion by photovoltaic solar cells with a device that sets a new world efficiency record. The new solar cell configuration developed by the engineers has pushed sunlight to electricity conversion efficiency up to 34.5% […]






University of New South Wales (UNSW) engineers have achieved the world’s highest efficiency using flexible solar cells that are non-toxic and cheap to make. They expect that ‘Zero-energy’ buildings – which generate as much power as they consume – are now much closer to practical reality. So far the promise of ‘zero-energy’ buildings been held […]






Washington State University (WSU) and University of Tennessee researchers led by the U.S. Department of Energy’s National Renewable Energy Laboratory believe they have reached a critical milestone in solar cell fabrication, helping pave the way for solar energy to directly compete with electricity generated by conventional energy sources. This milestone is based on improving the […]






MIT researchers have now demonstrated solar cells so thin, flexible, and lightweight that they could be placed on almost any material or surface, including your hat, shirt, or smartphone, or even on a sheet of paper or a helium balloon. Such a technology is the thinnest, lightest solar cells ever produced. The new process is […]






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 […]
