University of California, Berkeley scientists and their colleagues have developed a simplified architecture by applying a new mix of materials to a standard design that leads to efficiencies rivaling conventional silicon solar cells. The new architecture takes very few processing steps to produce an affordable solar cell with efficiencies comparable to conventional silicon solar cells. […]






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 […]






Ecole Polytechnique Fédérale de Lausanne researchers are pushing the limits of perovskite solar cell performance by exploring the best way to grow these crystals. On the other side of the world scientists at Hong Kong Polytechnic University report they have successfully developed perovskite-silicon tandem solar cells with the world’s highest power conversion efficiency of 25.5%. […]






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 […]
