Perovskite solar module, preparation method therefor, and solar panel

A preparation method for a perovskite solar module, comprising:

• providing a substrate;
• forming a plurality of perovskite solar devices on the substrate;
• applying, for each of the plurality of perovskite solar devices, a first encapsulation layer on a surface of the perovskite solar device facing away from the substrate, and a second encapsulation layer on sidewalls of the perovskite solar device;
• laminating a cover plate onto the surface of each of the plurality of perovskite solar devices via the first encapsulation layer, wherein an orthographic projection of each of the plurality of perovskite solar devices on the substrate falls within an orthographic projection of the cover plate on the substrate;
• and
• cutting the substrate and the cover plate to obtain a plurality of perovskite solar modules, each of the plurality of perovskite solar modules comprising a sub-substrate, a perovskite solar device and a sub-cover plate that are sequentially stacked in order, wherein the sub-substrate is obtained by cutting the substrate, and the sub-cover plate is obtained by cutting the cover plate.
