Abstract

The invention provides a semitransparent perovskite layer, a semitransparent perovskite photovoltaic module and a preparation method, and the preparation method comprises the steps: processing a first perovskite precursor layer with a structural pattern, carrying out the covering preparation of a second perovskite precursor layer, carrying out the annealing, converting a region with the first perovskite precursor layer into a perovskite layer, and carrying out the conversion of the region with the second perovskite precursor layer into the perovskite layer. And the area without the first perovskite precursor layer is a transparent layer, so that the semitransparent effect is achieved. According to the invention, the semitransparent perovskite layer is prepared in a direct processing mode, and transparent etching is realized without laser, so that the equipment cost is reduced, and the production process is simplified.

Description
