Stretchable CPV module with 15.4% efficiency
Japanese scientists have fabricated a prototype CPV panel that could be applied on spherical surfaces with a curvature radius of 100 mm, and under outdoor one-sun irradiation. The module is based on a silicone concentrator lens, a thermoplastic polyurethane sheet, and a rigid III–V triple-junction solar cell.
Testing CPM-based passive cooling for CPV systems
An international research team has tested change material heat sinks for heat management on a concentrator photovoltaic system. It found that increasing over height ratios lowers the formation of stratified liquid layers, which in turn reduces the potential hot spots in the upper part of the solar cell.
Scientists hit 21.6% perovskite cell efficiency using concentrator PV
An international research group achieved the result on a 9 sq mm, triple-cation based, n-i-p structured perovskite cell using low solar concentration levels. Device instability, however, remains a challenge.
