The team chose tungsten oxide (WO3) as a buffer layer based ... the two structures demonstrated that the addition of the BSF layer could increase the erformance of the CZTS solar cell.

which can in turn enhance the carrier collection efficiency of CZTS-based solar cells. In the future, their proposed approach could be applied to other wide-bandgap kesterite PVs, potentially ...

Engineers at Australia’s University of New South Wales (UNSW) have claimed to have achieved a new world record for photovoltaic efficiency using high-bandgap kesterite solar cells (CZTS).
