Problems solved by technology

[0003] However, due to the nature of the perovskite material itself is sensitive to water and oxygen, its efficiency will be greatly attenuated when exposed to air, which limits the commercialization process of perovskite solar cells. In order to overcome this problem, it is urgent to solve the problem of perovskite solar cells Advanced packaging technology can make the battery work stably and efficiently

Abstract

The present invention provides a packaging method of perovskite solar cell, which involves the field of solar cells. The battery uses ITO glass carved by specific specifications as a substrate, and ostellets osteotic materials are used as an absorption layer.PET glycol (PET) coverage membrane and transparent AB glue that is not significant on the effects of perovskite materials to encapsulate the perovskite battery to the greatest extent to ensure the stability of the perovskite battery batteryIt is obvious to improve, and the method is simple and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a packaging method for perovskite solar cells. Background technique [0002] Solar photovoltaic power generation has developed rapidly due to its advantages of safety, reliability, less geographical constraints, and easy integration with buildings. Organic-inorganic hybrid perovskites were first applied in the field of photovoltaics by Miyasaka et al. in 2009, in which CH 3 NH 3 PB 3 The cell as the light absorbing layer achieved a photoelectric conversion efficiency of 3.8%. In view of the excellent photoelectric properties of perovskite materials, in just a few years since then, perovskite solar cells have made great progress in photoelectric conversion efficiency, and now the highest efficiency has reached 22.7%. In addition, the raw material cost of organic-inorganic hybrid perovskite materials is very low, and devices can be prepared by solution method, which can rea...
