Challenges in fabricating all-perovskite tandem solar cells as modules rather than single-junction configurations include growing high-quality wide-bandgap perovskites and mitigating irreversible degradation caused by halide metal interdiffusion at the interconnecting contacts. We demonstrate efficient using scalable fabrication techniques. By systematically tuning cesium ratio of a methylammonium-free 1.8-electron volt mixed-halide perovskite, we improve homogeneity crystallization for...
Abstract Significant advancements in perovskite solar cells (PSCs) have been driven by the engineering of interface between absorbers and charge transport layers. Inverted PSCs offer substantial potential with their high power conversion efficiency (PCE) enhanced compatibility for tandem cell applications. Conventional hole materials like poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) poly(triaryl amine) (PTAA) not only constrain PSC but also elevate fabrication costs. In...
Perovskite Solar Cells In article number 2302280, Yi Hou and co-workers investigate self-assembled monolayer (SAM) growth models plasma treatment for conformal SAM growth, suppressing non-radiative recombination. This approach achieves 24.5% power conversion efficiency (stabilized at 23.5%) in inverted perovskite solar cells.
