Title:
TRANSPARENT CONDUCTIVE OXIDE THIN FILM AND HETEROJUNCTION SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2023/040120
Kind Code:
A1
Abstract:
Provided in the present application are a transparent conductive oxide thin film and a heterojunction solar cell, relating to the technical field of solar cells. The transparent conductive oxide thin film comprises a seed layer, an electrically conductive layer, and a protective layer. The seed layer comprises an indium tin oxide film or a gallium/aluminum co-doped zinc oxide film, the electrically conductive layer is a gallium/aluminum co-doped zinc oxide film, and the protective layer is an indium tin oxide film; the thickness of the indium tin oxide film in the transparent conductive oxide thin film is less than the thickness of the gallium/aluminum co-doped zinc oxide film. This can ensure the cell efficiency and reduce attenuation of the cell, and can also reduce costs.
