要約(日本語)：Methylammonium-free cesium/formamidinium perovskite solar cells (CsFA-PSCs) combined with carbon electrodes present a promising pathway toward low-cost, stable photovoltaics. However, interfacial defects limit their performance and durability. In this work, we present our recent advancements in passivation strategies. Optimized annealing promotes PbI₂ formation, while formamidinium iodide (FAI) post-treatment decreases trap states and enhances device efficiency. Building on these results, we are currently developing a porphyrin-based molecule for targeted passivation of CsFA films. This molecular approach offers new opportunities for improving the efficiency and long-term stability of carbon-based PSCs.
