摘要

Over the past decades,the emergence of photovoltaics (PV) alleviates the energy crisis and environmental pollution of fossil fuels.Compared to the large-scale silicon-based PV technology,thin-film PV technology is still just a newcomer.Thin-film solar cells need only several microns thickness to absorb most of the sunlight effectively,enabling the application in flexible substrates.The advantages in portable wearable devices coupled with the increasing efficiency facilitate its development and it can be expected that thin-film solar cell technology will rapidly enter and occupy the market after a few years.Among various thin-film solar cell absorber materials,the kesterite semiconductor Cu2ZnSn(S,Se)4 (CZTSSe) is composed of earth-abundant and environmentalfriendly elements while possessing promising optical-electrical properties.Therefore,CZTsse thin-film solar cells are regarded as the dark horse of next-generation photovoltaic technology [1].
