key aspects on development of high efficiency heterojunction and ibc heterojunction solar cells towards 22 efficiency on industrial size
Abstract
In this paper, we show the latest results of CEA-INES on the development of HET and IBC-HET solar cells. We have focused the research on the optimization of the amorphous (a-Si:H) and TCO layers to increase Jsc and FF values on HET cells. Moreover, we have fabricated silver –free HET solar cells with a Copper electroplating metallization. We also show our latest results obtained with a new structure combining HET and IBC (Interdigitated Back Contact) concepts: the SLASH IBC cell (Structuring by Laser Ablation of Silicon Heterojunction). Short-circuit current issues for both standard - and IBC – HET solar cells are discussed in this paper. Efficiencies higher than 22% have been achieved on 100 cm2 standard HET solar cells and close to 20% on 25 cm2 SLASH IBC cells. 27th European Photovoltaic Solar Energy Conference and Exhibition; 576-579
