Fabrication Of Cu2Znsnse4 Thin-Film Solar Cells By A Two-Stage Process, Yejiao Wang

USF Tampa Graduate Theses and Dissertations

Copper zinc tin selenide (Cu₂ZnSnSe₄ or CZTSe) is a quaternary compound semiconductor material that has attained more and more attention for thin film photovoltaic applications. CZTSe is only comprised of abundant and non-toxic elements. People have concerns about availability and cost of indium from CIGS and tellurium from CdTe, also about cadmium’s toxicity. These concerns have promoted CZTSe as an alternative thin film solar cell material. The major issues about CZTSe absorber fabrication are: tin loss during selenization process and existence of secondary phases. Recent improvements of CZTSe absorber have increased the efficiency of CZTSe thin film …
