Thin film CZTSe solar cell achieves 9.7% efficiency
Described as an important step in the development of thin film solar cells, imomec and Solliance have developed a 1cm2 CZTSe (Cu2ZnSnSe4) based solar cell with an efficiency of 9.7%.
"This is a big win for us," said Marc Meuris, Solliance's programme manager. "Our efficiencies are the highest in Europe and approaching the world record for this type of thin film solar cell. We look forward to further advancing R&D to help bringing to market sustainable energy sources."
CZTSe is an emerging solar cell absorber and has properties similar to CZTS (Cu2ZnSnS4). Imomec, imec and Solliance have defined a path towards further improving the layers and cell structures of CZTSe and CZTS absorbers to produce solar cells with 20% efficiency.
