An alternative structure (Glass/SnO2/ZTO/CdS:O/CdTe1−𝑥S𝑥/CdTe) of a reference solar cell is presented. Cadmium Telluride (CdTe) solar cells are widely used because of various advantages such as better stability, low cost, high efficiency. Back Surface Reflector (BSR) is introduced between absorber layer and back metal contact. The BSR layer with distinct band gap material has been used to decrement the minority carrier recombination at the back contact. Based on the new model, this paper has shown improved fabrication parameters by using Cu2Te material as BSR layer. Various other parameters like bandgap, open-circuit (Voc), short-circuit current density (Jsc), Fill-factor (FF) and quantum efficiency (Eff) has been analysed. The traditional structure of solar cell has been modified by introducing CdS: O window layer (thickness-25nm) having varying wide range of band gaps. This layer influence the parameters of reference model, which is easily observed after the simulation. Several J-V characteristics and efficiency has been found quite better and high compared to the reference cell. Cu2Te material as BSR layer shown impressive improvement in conversion efficiency of 3.671% as compared to the reference model having no BSR layer. Which indicates the possibilities of future enhancement of properties of Cds/CdTe solar cell.
