Abstract

Perovskite based solar cells without the hole conducting material and the evaporated metal electrode would reduce the materials cost of the photovoltaic technology. In this study, we report fully printable, organic-inorganic metal-halide perovskite solar cells with conversion efficiencies exceeding 7%. These fully printable devices were fabricated in a planar structure by directly printing a graphite film on top of an underlying CH3NH3PbI3 perovskite layer. This fabrication method is attractive for making low cost perovskite solar cells as no precious metals and expensive hole conducting materials are required. Both planar and mesoscopic architectures were compared, with the planar structure better compatible to the graphite electrode. Using the planar structure, it was found that a pure graphite layer of approximately 20 μm produced good device performance.
