Title:
THIN FILM, THIN FILM SOLAR CELL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/011259
Kind Code:
A1
Abstract:
The embodiments of the present invention relate to the technical field of thin films, and relate to a thin film, a thin film solar cell and a preparation method therefor; the technical problem to be mainly solved is the water-blocking properties of a cover film layer being poor. The technical solution that is mainly employed is as follows: the preparation method for a thin film comprises: forming a first cover layer on a surface of a resin film layer by employing a coating process so that the first cover layer covers surface holes on the surface of the resin film layer; forming a second cover layer of an inorganic material on the first cover layer by employing a deposition process. Compared with the existing technology, in the embodiments of the present invention, since the surface holes of the resin film layer are covered by the first cover layer, an inorganic film layer formed by the second cover layer of an inorganic material thus has good water-blocking performance. Thus, the thin film and thin film solar cells have high water-blocking performance.
