Abstract: Organic-inorganic hybrid perovskite (PVK) solar cells have become a promising candidate in the photovoltaic field due to their high extinction coefficient, high carrier mobility, low exciton binding energy and tunable band gap, etc. Perovskite solar cell devices have the advantages of simple structure, efficient fabrication process and low material cost, which are expected to replace traditional silicon cells in the future. The charge transport layer is a key part of perovskite solar cells. In this work, the effects of different underlying charge transport layers on the surface potential, carrier recombination and photovoltaic performance of perovskite films were investigated in detail. Scanning Kelvin probe microscopy (SKPM) results show that the conductivity type of the underlying charge transport materials an obviously change the surface potential of the perovskite films. This result confirms that perovskite film is a weak doped semiconductor films. When deposited on electron transport layer coated substrate, the perovskite film display a high surface potential and small work function, and exhibits n-type conductivity. On the contrary, when deposited on hole transport layer coated substrate, the film has a low surface potential and large work function. Based on the analysis of the properties of perovskite films on different charge transfer layers, an obvious relationship between surface photovoltage and the performance of charge transport layer can be ascertained. Moreover, we researched the correlation between the thermal stability of the perovskite film and their surface photovol-tage, and concluded that the change of surface photovoltage could partly reflect the thermal stability of thin film. It is concluded that bromide ion (Br-), methylammonium chloride (MACl) and cesium ions (Cs+) could improve thermal stability for perovskite films.
