AI Technical Summary

Technical Problem

During the use of perovskite solar cells, after the packaging structure is damaged, the lead ions cannot be effectively fixed, which can easily cause lead leakage, affect the stability and service life of the battery, and cause damage to the environment.

Method used

A package structure with a lead absorbing layer is formed outside the perovskite solar cell. By coating the lead absorbing material on the surface of the glass cover plate and annealing, a lead absorbing layer is formed and laminated on the photovoltaic adhesive film to form a package structure.

Benefits of technology

It effectively prevents lead leakage in the perovskite layer, improves the stability and service life of the battery, and reduces environmental pollution, which is cheap and simple.

Abstract

The embodiment of the invention provides a perovskite solar cell packaging method and packaging structure. The method comprises the following steps: providing a perovskite solar cell, an insulating colloid, a photovoltaic adhesive film and a glass cover plate; mounting the insulating colloid on the side surface of the perovskite solar cell; covering the backlight surface of the perovskite solar cell with the photovoltaic adhesive film; forming a lead absorption layer on the surface of the glass cover plate; and laminating the surface, with the lead absorption layer, of the glass cover plate on the photovoltaic adhesive film to obtain the perovskite solar cell packaging structure. According to the perovskite solar cell packaging method and packaging structure provided by the embodiment of the invention, the packaging structure of the lead absorption layer with a metal ion chelation effect is formed outside the perovskite solar cell, so that lead in the perovskite layer is prevented from leaking. The method is simple, effective and low in cost, and the stability, the service life and the environmental friendliness of the perovskite solar cell are improved.
