Recent advances on monolithic perovskite‐organic tandem solar cells

“…[ 24 ] Tan et al fabricated an ICL consisting of PM6/MoO 3 /Ag/PFM‐Br, achieving a record‐breaking PCE of 24.07% in inorganic perovskite‐organic TSCs, which is among the best results for these types of solar cell. [ 76 ] Wang et al employed PBDB‐T‐Si, D18, and polyTPD as HTL within the ICL to demonstrate the critical role of HTL. [ 23 ] The HTL of polyTPD was proved to be the optimal choice due to its minimal parasitic absorption, moderate hole mobility, and quasi‐Ohmic contact properties, significantly suppressing the charge accumulation and voltage loss within the tandem device.…”

“…This can be ascribed to that most of the high-performance WBG PSCs reported in the literature are with p-i-n type device structure, and existing n-i-p NBG OSCs still suffer more severe efficiency losses than the p-i-n OSC counterparts. [33,34] Cesium (Cs)-based all-inorganic perovskites with a WBG are commonly used as the front subcells for n-i-p type perovskite-organic TSC, while organicinorganic mixed halide perovskites are utilized for p-i-n type configurations. However, all of them encounter significant issues related to voltage loss attributed to phase segregation.…”
