Abstract: A perovskite solar cell with a local semi-opening passivation contact structure, which at least includes a charge transport layer and a perovskite layer. An insulating or low-conductivity material layer is provided between the charge transport layer and the perovskite layer, and the insulating or low-conductivity material layer is of a continuous or discontinuous island structure. By constituting the local semi-opening passivation contact structure between the charge transport layer and the insulating or low-conductivity material layer, a contact area between the charge transport layer and the perovskite layer can be reduced and non-radiative recombination at an interface can be reduced without affecting extraction and transport of carriers between the perovskite layer and the charge transport layer, which avoids conflict between passivation and charge transport, thus achieving a high open-circuit voltage and a high filling factor without reducing current density and making the passivation layer be set with a large thickness range.
