摘要：Perovskite solar cells (PSCs) are promising low-cost photovoltaic technologies with high solar-to-electric power conversion efficiency (PCE). The heterojunction structure between perovskite and charge extraction layers is crucial to the photovoltaic performance of PSCs. Here, we report efficient inverted-structured PSCs with a perovskite–fullerene graded heterojunction (GHJ), in which the electron-accepting material is distributed in the perovskite layer with a gradient. This structure can enhance the PCE as it improves the photoelectron collection and reduces recombination loss, especially fo
