Abstract

The invention discloses a method for manufacturing a flexible-film solar battery, which comprises the following steps of: providing a hard carrier plate; forming an isolated protecting layer on the surface of the hard carrier plate; forming a film solar-battery layer system with internal cascade on the surface of the isolated protecting layer; combining or forming a flexible bearing layer on the surface of the film solar-battery layer system; and integrally isolating the flexible bearing layer and the film solar-battery layer system from the hard carrier plate. In the invention, the flexible-film solar battery can be directly manufactured on the surface of the hard carrier plate, such as glass, without a traditional and expensive flexible substrate with high requirements on physicochemical characteristics or a complicated process for manufacturing the flexible-film solar battery by firstly adhering the flexible substrate to the surface of the hard carrier plate and then continuing to deposit a film, and the manufacturing method is a revolutionary method for directly manufacturing the large-area internally-cascaded flexible-film solar battery on the hard carrier plate.

Description

technical field

[0001] The invention relates to the technical field of solar cells, in particular to a method for manufacturing a flexible thin-film solar cell. Background technique

[0002] Energy is the driving force for the development of human society and an important material basis for the development of the national economy and the improvement of people's living standards. Conventional energy (mainly fossil energy such as coal, oil, and natural gas) widely used at present is limited, and years of excessive development and utilization have caused serious environmental problems, restricting economic and social development. Therefore, the development of renewable energy is one of the key issues related to the national sustainable development strategy. Among various renewable energy sources, solar photovoltaic power generation technology is the fastest-growing and most cutting-edge research field in the field of solar energy utilization in recent years. Among them, thin-...
