Abstract |
|
|
| This study investigates cesium-based halide perovskite solar cells with varying halides (Br, I, Cl) to assess their impact on device performance. By comparing CsPbBr3, CsPbI3, and CsPbCl3 compositions, the work explores their optical and structural properties using numerical simulation and available experimental data. The device architecture incorporates a graphene (Gr)-based electron transport layer (ETL) to enhance electron mobility and reduce recombination losses, while the hole transport material (HTM) layer is constructed using carbon nanotubes (CNTs) to improve hole extraction and charge transport. The results show that halide substitution significantly influences the bandgap and overall device behavior. Among the studied compositions, CsPbI3 achieved the highest power conversion efficiency (PCE) (19.9), the highest short- circuit current density Jsc (24.9), and the highest fill factor FF (72.0), making it the most promising candidate for high- performance perovskite solar cells.
