A perovskite solar cell with a local semi-open passivation contact structure, at least comprising a charge transport layer and a perovskite layer, an insulating or low-conductivity material layer being provided between the charge transport layer and the perovskite layer, and the insulating or low-conductivity material layer being a continuous or discontinuous island structure. By constituting the local semi-open passivation contact structure between the charge transport layer and the insulating or low-conductivity material layer, the charge transport layer and the perovskite layer have a reduced contact area therebetween and decreased non-radiative recombination at an interface while not affecting extraction and transport of carriers between the perovskite layer and the charge transport layer, thus avoiding the conflict between passivation and charge transport, which allows a high open-circuit voltage and fill factor, a unreduced current density and a passivation layer having a thickness settable within a large range; high temperature is not required during the preparation process and the characteristic of local contact will not affect the light absorption of the perovskite layer.
