Concentrator PV Shows Peak Performance – Module Efficiency Reaches 41.4 %

Concentrator Photovoltaics (Concentrator PV) has by far achieved the highest efficiency for the conversion of sunlight into electricity. The basis for this latest achievement lies in the special multi-junction solar cells as well as the perfect interplay between the cell and the module optics. In the EU-funded project CPVMatch, a consortium of research institutions and […]

New records in perovskite-silicon tandem solar cells through improved light management

Tandem solar cells made of silicon and metal halide perovskite compounds can convert a particularly large portion of the solar spectrum into electrical energy. However, part of the light is reflected and is thus lost for purposes of energy conversion. Using nanostructures, the reflection can be reduced significantly ensuring that the solar cell captures more […]

Largest solar power study to date discovers 25% power loss

Researchers at the University of Huddersfield have undertaken the largest solar power study to date into the effectiveness of solar panels across the UK and discovered that parts of the country are suffering an overall power loss of up to 25% because of the issue of regional ‘hot spots’. Hot spots were also found to […]
