摘要:
The surface defects of nickel oxide (NiO x ) and its interfacial redox reactions with perovskites often impede the efficiency improvement of inverted perovskite solar cells (PSCs). To address these issues, we designed ((9H-fluoren-9-ylidene)methyl) cyanophosphonic acid (FY-CPA) with a rigid backbone as an optimal multi-dentate anchoring (MDA) molecule to enhance the anchorage with bottom NiO x by forming tetradentate binding and parallel orientation. Dense and uniform coverage of FY-CPA at the NiO x /perovskite interface was achieved through in situ deposition, which can minimize interfacial r...
