Abstract
High-efficiency fullerene-free planar perovskite solar cells (PSCs) consisting of hexadecafluorophthalocyaninatocopper (F16CuPc) as electron conductors are firstly reported. In the condition of using F16CuPc as a direct replacement for fullerene that universally employed in planar PSCs with an architecture of ITO/hole transport layer (HTL)/perovskite/electron transport layer (ETL), PSCs exhibit quite satisfactory photovoltaic performances. The best PSC with F16CuPc ETL presents a power conversion efficiency of 12.62% with a short-circuit current density (JSC) of 19.97Â mA/cm2, an open-circuit voltage (VOC) of 0.93Â V and a fill factor (FF) of 0.68. Such performance is comparable to the C60-based PSCs and higher than that of the PCBM-based PSCs.
