Butyldithiocarbamate Acid Solution Processing: Fundamentals and Its Application in Chalcogenide Thin Film Solar Cells

Abstract

Solution method has been wildly explored in chalcogenide photovoltaics because of its simple process and low cost. Currently, the solvents used in many solution processes are usually toxic and have low solubility to metal chalcogenide such as hydrazine and diamine–dithiol solvents, thus limiting their development and large-scale applications. Butyldithiocarbamate acid (BDCA), a kind of relatively friendly solvent compared with commonly used hydrazine and diamine–dithiol solvents, can dissolve various metal oxides and metal hydroxides, making it promising to deposit metal chalcogenide films. In this review, we introduce the fundamental chemical property of BDCA in details, and summarize the application of BDCA solution method in high-efficient and low-cost photovoltaics, including Sb2S3, Sb2S3-xSex, CuSbS2, Cu(In,Ga)(S,Se)2 and Cu2ZnSn(S,Se)4 thin film solar cells. We hope this review can stimulate more researchers to explore more metal chalcogenides and use them in different fields such as photocatalysis, photodetector and so on.
