New process increases efficiency of CIGS bifacial thin-film solar cells
Researchers from the Swiss Federal Laboratories for Materials Science and Technology (Empa) have developed a new low-temperature production process for bifacial thin-film solar cells based on copper indium gallium diselenide (CIGS). It resulted in record yields of 19.8% for front lighting and 10.9% for rear lighting.
International consortium claims 25% efficiency for perovskite CIGS solar cell
Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² perovskite tandem solar cell. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.
