  • PROCESS FOR PRODUCING A P-N JUNCTION IN A CZTS-BASED PHOTOVOLTAIC CELL AND CZTS-BASED SUPERSTRATE PHOTOVOLTAIC CELL
    Publication number: 20160163896
    Abstract: The invention relates to a process for producing a p-n junction in a photovoltaic cell made of thin CZTS-based films, comprising: a) a step of depositing a film of precursors containing zinc, tin and copper, the amount of zinc being larger than that required to convert the precursors into a CZTS type photovoltaic material and b) a step of annealing the precursors, under a sulphur- and/or selenium-containing atmosphere, so as to obtain a photovoltaic film made of CZTS and a buffer layer made of ZnS1-xSex, where x is comprised between 0 and 1.
