摘要

CZTS, is a good absorber material which also shows electrocatalytic behavior thus making it a suitable candidate for use as counter electrode for DSSCs. At the same time it is the long term stability of the counter electrode which is the primary motivation for carrying out this work. Herein, CZTS is electrodeposited on FTO coated glass and used as counter electrode to fabricate DSSCs. Sealed DSSCs were subjected to ageing in dark and under illumination at room temperature and cells were examined periodically using I-V and EIS measurements. CZTS counter electrode based DSSCs showed relatively stable performance after 120 days of ageing under illumination with slight decrement in the electrocatalytic activity of CZTS.
