CZTSSe BASED SOLAR CELL WITH TIN SULLPHIDE (Sn2S3) BACK SURFACE FIELD LAYER

The present disclosure pertains to a CZTSSe based solar cell (100). The solar cell(100) includes a tin sulphide (Sn2S3) layer(102) embedded as a Back Surface Field(BSF) for a CZTSSe layer (104), where the CZTSSe layer (104) is fabricatedabove the (Sn2S3) layer (102). The solar cell (100) includes a cadmium sulphide(CdS) layer (106) fabricated between the CZTSSe layer (104) and a zinc oxide(i-10 ZnO) layer (108), where the zinc oxide (i-ZnO) layer (108) is fabricated above theCdS layer (106). The solar cell (100) includes a zinc oxide (ZnO) layer (110)fabricated above the i-ZnO layer (108), where an interface of the CZTSSe layer(104) and the Sn2S3 layer (102) facilitates restricting flow of a set of electrons.The set of electrons are directed towards the CZTSSe layer (104), and where the15 Sn2S3 layer (102) facilitates increasing power conversion efficiency of the solarcell (100).
