Perovskite solar cell module package structure and package method

Abstract

The invention discloses a perovskite solar cell module package structure which is used for packaging a plurality of perovskite solar cells into a photovoltaic module. The plurality of perovskite solar cells are connected in series and / or in parallel through inter-connected conductive circuits, the perovskite solar cell module package structure comprises a backside substrate, a package adhesive and front glass and is characterized in that the package adhesive comprises a solar cell package adhesive and a module package adhesive, the solar cell package adhesive is used for packaging a single solar cell, the module package adhesive is used for jointly packaging the plurality of solar cells, the solar cell package adhesive adopts a colorless and transparent epoxy package adhesive, an organic silicon package adhesive, a polyurethane package adhesive or an ultraviolet photocuring package adhesive, and the module package adhesive adopts an ethylene-vinyl acetate copolymer and a polyvinyl butyral or ethylene-octene copolymer and fills a space among the backside substrate, the perovskite solar cells, the inter-connected conductive circuits, the solar cell package adhesive and the front glass. The invention also provides a perovskite solar cell package method.

Description

technical field [0001] The invention relates to a packaging structure of a solar cell assembly, in particular to a packaging structure of a perovskite solar cell assembly and a packaging method thereof, belonging to the technical field of solar cell assemblies. Background technique [0002] With the increasingly serious problems of the global ecological environment and energy shortage, solar photovoltaic power generation has attracted widespread attention from all countries. At present, the cell conversion efficiency of industrialized crystalline silicon is stable at about 19% (monocrystalline) and 17-18% (polycrystalline), and there are technical and cost bottlenecks in further improving efficiency. Although some high-efficiency silicon cell technologies have been continuously proposed, the preparation process of these high-efficiency solar cells is complicated, the quality is not easy to control in mass production, and the requirements for equipment are high. Therefore, it...
