Abstract
In CdTe solar cell, CdTe absorber layer needs ohmic contact having work function greater than 5.7eV. No metals can have such large work function to match properly with CdTe absorber layer. Low resistance is required between CdTe layer and back contact for good performance and long stability of CdTe based solar cell. So there is a need of inserting back surface field layer to reduce the resistance between CdTe layer and back contact. This study highlights the effect of ZnTe BSF layer on the performance of solar cell. In this study two cell were simulated by SCAPS-1D simulator. From analysis it can be seen that with the help of BSF layer high efficiency as well as high stability can be achieved
