Abstract

The invention discloses a method for manufacturing a flexible transparent thin-film solar cell. The transparent thin-film solar cell is applied on the side of the display surface of a flexible display module to provide power for the flexible display module. The method includes the following steps: Make a flexible transparent film on the substrate; sequentially make a front electrode, a photovoltaic absorber layer, a back electrode and a first protective layer on the flexible transparent film to form a transparent thin film solar cell; attach an OCA adhesive layer to the transparent thin film solar cell; invalidate the edge Cut the area and peel off the flexible solar cell film from the rigid substrate to form a flexible transparent thin film solar cell large plate; attach the second protective layer on the outside of the flexible transparent film, and then perform single grain cutting, binding and Function and appearance inspection, the transparent thin film solar cell can be applied to 3D display and flexible display modules, and the production of the flexible transparent film is simpler and more reliable.

Description

technical field [0001] The invention relates to the technical field of manufacturing transparent thin-film solar cells, and more particularly relates to a method for manufacturing flexible transparent thin-film solar cells. Background technique [0002] With the increasing demand for energy and the continuous development of thin-film solar cell technology, thin-film solar cells are applied to display modules (such as wearable electronic products), and the principle of light-to-electricity conversion is used to power the display module. Technology is being used more and more widely. [0003] Generally, a thin film solar cell includes a substrate, a front electrode, a photovoltaic layer and a back electrode stacked in sequence, the thin film solar cell covers the display module and the back electrode side of the thin film solar cell faces the display module. The display module includes a middle display area and a non-display area surrounding the display area. The thin-film so...
