Abstract
The production and commercialization of solar cells should meet such social criteria as price affordability, environment friendly, stability, and high efficiency of established materials.Various solar cells have been suggested and investigated in the past; but in this work, CZTS-Perovskite tandem solar cell having a model “CZTS/PSC/CZTS/ZnO/FTO” was taken from the reported work as a reference. Furthermore, inserting the CdS as a buffer layer with the new model, “CZTS/PSC/CZTS/CdS/ZnO/FTO” was simulated with SCAPS-1D software. Moreover, it was observed that the effect of CdS enhanced the tandem device efficiency from the base case of 22.57% without the CdS buffer layer to 25.95% with CdS and carried out further optimizations. This improvement is beneficial for CZTS-Perovskite tandem solar cells. The J-V characteristics curve and energy band diagram was generated using this model. Later on, with this new model, the effect of the thickness of CZTS layer on the solar cell’s performance was investigated. So, the thickness also significantly affected the characteristic parameters of the solar cell as well as the J-V characteristics curve. Hence, a photo-conversion efficiency of 25.95% with Voc 1.18 V, Jsc 24.79 mA/cm2, and FF 88.36%, the obtained results demonstrating that the proposed CZTS-perovskite tandem solar cell may concrete the way for the production of low-cost and more efficient photovoltaic applications.
