Thin-film solar photovoltaic auto glass component and preparation method thereof

Abstract

The invention discloses a thin-film solar photovoltaic auto glass component. The photovoltaic auto glass component orderly comprises an inner windscreen, a thin-film solar cell and an outer windscreen from the inner side to the outer side of an automobile, wherein the thin-film solar cell comprises a substrate, a TCO front electrode, a photoelectric conversion layer and a TCO back electrode; the TCO front electrode is arranged on the substrate; the photoelectric conversion layer is arranged on the TCO front electrode; the TCO back electrode is arranged on the photoelectric conversion layer; the substrate is toughened or non-tempered thin glass; the thickness of the substrate is 0.2-0.7mm; the thin-film solar cell is a semi-transparent silicon film cell; the light transmittance of the thin-film solar cell is higher than 50%. Correspondingly, the invention also provides a preparation method of the thin-film solar photovoltaic auto glass component. In the technical scheme provided by the invention, the thin-film solar cell between two windscreens is high in reliability, is a flexible cell, and can be compatible with the curve surfaces of the windscreens. By adopting the method disclosed by the invention, the thin-film solar photovoltaic auto glass component with low cost and high efficiency can be prepared.

Description

technical field [0001] The invention belongs to the field of solar cell manufacturing and application, and in particular relates to a thin-film solar photovoltaic automobile glass assembly. Background technique [0002] Thin-film solar cells have beautiful appearance and can be deposited on large-area substrates (such as glass) to collect inexhaustible solar energy, so they have become an important technology in the field of photovoltaics. Thin-film solar cells have a low temperature coefficient and good low-light effects, which are very suitable for some differentiated application fields. In particular, large-area flexible solar cells made of thin-film solar cells combined with glass have incomparable advantages over crystalline silicon cells. Glass has been widely used in various fields of people's lives, and its combination with thin-film solar cells has been used in a large number of applications, such as Building Integrated Photovoltaic (BIPV). [0003] In the field o...
