| Abstract [eng] |
Recent years have reached intense research and development efforts of perovskite solar cells (PSCs), due to their growing efficiency [1]. Self-assembled mono-molecular layers have been proven to be useful as the HTL for highefficiency Pb-PVK PSCs.[2] The molecules for these monolayers have p-type group/linker group/anchor groups. The molecules with phosphonic acids as the anchor group (PACz) are widely used in PSCs. Poly[bis(4‐phenyl) (2,4,6‐trimethylphenyl) amine] (PTAA) is commonly employed as a hole transporting layer for FA0.8Cs0.2PbI1.8Br1.2. However, since the hydrophobic surface sometimes suppressed the crystal growth of the FA0.8Cs0.2PbI1.8Br1.2 layer and the Fermi level of PTAA is not well matched with that of perovskite film, the efficiency of the WBG Pb-PVK PSCs consisting of PTAA was not high. In this study, a series of PACz-based SAMs with different functional groups (I-3PACz, 9p-3PACz, 2M3P-3PACz) were synthesized to modify the interface between PTAA and perovskite film. The structures of compounds are shown in Figure 1. [...]. |
