Thin-film photovoltaic cell and manufacturing method thereof

Abstract

The invention discloses a thin-film photovoltaic cell and a manufacturing method thereof. The thin-film photovoltaic cell comprises a transparent substrate and a photovoltaic unit which is arranged onthe transparent substrate and faces towards an electronic display modules, the photovoltaic unit includes a front electrode arranged on the transparent substrate, a light absorption layer arranged onthe front electrode and a back electrode arranged on the light absorption layer, and the back electrode is provided with a first blackened metal conductive layer on the surface facing towards the transparent substrate, thereby enabling the color of the photovoltaic unit of the thin-film photovoltaic cell to be closer to the background color of the electronic display module, and achieving an effect of black integration of the two.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, and more specifically relates to a thin-film photovoltaic cell and a manufacturing method thereof. Background technique [0002] Solar energy, as the renewable energy with the most extensive sources and the largest reserves in the energy field, has been widely concerned by people. With the continuous development of thin-film photovoltaic cell technology, the application fields of thin-film photovoltaic cells are becoming wider and wider, for example, thin-film photovoltaic cells are directly arranged on electronic products that can be displayed. Existing thin-film photovoltaic cells use a photovoltaic layer on a transparent substrate to realize photoelectric conversion. However, the color of the photovoltaic layer is usually purple-red or dark green, which is different from the background color of the electronic display module (usually black, gray, etc.). Black or dark purple) have large c...

AI Technical Summary

Problems solved by technology

Existing thin-film photovoltaic cells use a photovoltaic layer on a transparent substrate to realize photoelectric conversion. However, the color of the photovoltaic layer is usually purple-red or dark green, which is different from the background color of the electronic display module (usually black, gray, etc.). Black or dark purple) have large color differences, which makes it impossible for thin-film photovoltaic cells to obtain an integrated black display effect when used in this type of electronic display module, which reduces the user experience of consumers.
