Perovskite solar cells are considered to be the upcoming star of thin film solar cells, exhibiting rapidly rising power conversion efficiencies (PCE). The active layer consist of the organic-inorganic perovskite structure CH3NH3PbI3. The perovskite is sandwiched between a electron and hole transport layers which allows the selective extraction of the different types of charge carriers to the respective contacts of the solar cell. In this study different structures of solar cells, including different combinations of selective transport layers such as PEDOT:PSS and MoO3 for hole transport or BCP, BPhen and Ca for electron transport were investigated concerning efficiency, hysteresis and long-term stability. Finally, the device stability of silver and gold as cathode material was inspected.
