To minimize losses in perovskite-silicon tandem solar cells, we apply optical modeling techniques that require precise optical constants obtained through methods like spectrophotometry and ellipsometry. Our research focuses on validating optical properties to reduce losses, thereby improving overall efficiency compared to single-junction cells. Recent developments have highlighted perovskites with wide bandgaps. Achieving current matching in two-terminal devices is essential due to interference effects in multi-layered tandems. Extensive modeling investigated varying bandgaps and pyramid heights to attain current matching, demonstrating that a 1.7 eV bandgap perovskite can achieve high efficiency. Reducing losses can further enhance performance.
