文摘

CZTS thin films and solar cells with different Cu content are prepared. The secondary phases can be suppressed by manipulating the Cu content. The fluctuating potential model is confirmed by photoluminescence measurement. The effects of Cu composition on the properties of CZTS solar cells are studied.
