| 概要 |
The eco-friendly and highly stable lead-free MAGeI_3 perovskite solar cell has proved itself as a potential candidate for conventional lead-based perovskite solar cells with high efficiency. In this p...aper, numerical simulation has been performed over MAGeI_3 solar cell with three different Electron Transport Layer (ETL) and Hole Transport Layer (HTL) materials to obtain the best combination of ETL/perovskite/HTL layers using the solar cell simulation tool SCAPS-1D. The best performance has been found for the ITO/ZnO/MAGeI_3/NiO_x structure with an efficiency of 21.19% (V_<oc> of 1.89 V, J_<sc> of 16.11 mA/cm^2, and FF of 69.57%) due to the higher bandgap and better carrier mobility of these two ETL and HTL materials. The thickness optimization indicated that a thickness below 1000 nm is suitable for better performance which also leads to a good indication of making a lightweight solar cell. This study indicates that the use of low-cost and environment-friendly ZnO and NiO_x with non-toxic MAGeI_3 perovskite has the potential to obtain a high-efficiency eco-friendly solar cell.続きを見る
