Perovskite solar cell module

Abstract

The invention discloses a perovskite solar cell module. The structure is a sandwich structure of 'conductive glass/electronic transmission body/multifunctional nickel net//electronic transmission body/conductive glass', and specifically comprises upper-layer conductive glass, lower-layer conductive glass, a multifunctional nickel net, an upper-layer electronic transmission body, a lower-layer electronic transmission body, an electrode and a glass adhesive. According to the structure, the perovskite absorption layer can be in full contact with the electron transmission body, electrons can be rapidly guided out from the two pieces of conductive glass, and the electron transmission efficiency is greatly improved; The interface contact of the perovskite absorption layer/hole transport layer can be increased through the net structure, and the hole transport efficiency is promoted. In addition, the whole perovskite absorption layer is completely in a closed state by tightly packaging the battery assembly, so that the environmental stability of the whole battery assembly is improved. The perovskite solar cell module has the advantages of being simple in structure, reasonable in design, high in practical value, low in cost, convenient and fast to assemble and the like, and is particularly suitable for being used as a perovskite solar cell module.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a perovskite solar cell assembly. Background technique [0002] As the global energy and environmental problems become increasingly prominent, the human demand for clean energy is becoming more and more urgent. Among various clean energy sources, solar energy is considered to be one of the most competitive clean energy sources due to its inexhaustible and inexhaustible advantages. The development of low-cost and high-stability solar cells has always been a challenge for scientists. pursuit of goals. Among various types of solar cells, silicon-based solar cells dominate the commercial solar cell industry due to their high photoelectric conversion efficiency and stable performance, but the necessary thickness of silicon wafers makes it impossible to significantly reduce production costs. Organic solar cells are cheap, but the stability of their photovoltaic effect is poor. C...

Problems solved by technology

There are many factors that affect the short-circuit current of perovskite solar cell components. On the one hand, there are defects on the surface of the hole transport layer of perovskite solar cells, resulting in a high recombination rate of electrons and holes, and the cell component has only one surface. The electron transport layer, the collection efficiency of electrons and holes is low, resulting in the general low short-circuit current of perovskite solar cell modules
