PEROVSKITE SOLAR CELL, DUAL LAYER METAL ELECTRODE AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/090824

Kind Code:

A1

Abstract:

A perovskite solar cell, a dual layer metal electrode used for a perovskite solar cell and a preparation method therefor. The perovskite solar cell comprises a glass substrate (3), a transparent conductive electrode (4), a hollow transmission layer (5), a perovskite thin film (6), an electron transmission layer (7) and a dual layer metal electrode; the dual layer metal electrode comprises a first metal thin film layer (1) and a second metal thin film layer (2), the preparation method therefor comprising: depositing the first metal thin film layer (1) on a side surface of the electron transmission layer (7), and depositing the second metal thin film layer (2) on the first metal thin film layer. By means of depositing a first metal thin film layer having chemical inertness on the electron transmission layer by low-temperature vacuum evaporation, and providing a second metal thin film layer having high conductivity on the first metal thin film layer, the permeation of moisture may be effectively isolated and the chemical corrosion of the second metal thin film layer may be reduced without reducing the efficiency of photoelectric conversion, being beneficial in improving the stability of a perovskite solar cell.
