Hexadecafluorophthalocyaninatocopper as an electron conductor for high-efficiency fullerene-free planar perovskite solar cells
High-efficiency fullerene-free planar perovskite solar cells (PSCs) consisting of hexadeca-fluorophthalocyaninatocopper (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 19.97 mA/cm(2), an open-circuit voltage (V-oc) of 0.93 V and a fill factor (FF) of 0.68. Such performance is comparable to the C-60-based PSCs and higher than that of the PCBM-based PSCs. (C) 2016 Elsevier B.V. All rights reserved.
