Abstract
In this work, investigation of a silicon-based tandem heterojunction solar cell was iterated via numerical modeling. The tandem cell was split into a top metal oxide and bottom c-Si subcell, and each subcell was analyzed and compared with experimental data. For the top subcell, Silvaco Atlas was used to ascertain optimum materials for the buffer layer and their impact on the cell performance. For the bottom subcell, a Quokka 2 model has be used to evaluate and compare current-voltage and quantum efficiency curves with experimental data. Transfer matrix algorithm was used to ascertain top subcell optical field characterization. The buffer layer materials for the ZnO/Cu2O subcell that yielded best cell performance are presently TiO2 and Ga2O3 while the Quokka 2 model presents a good fit with the experimental curves.
