Flexible thin film solar cell and manufacturing method thereof

Abstract

The invention discloses a flexible thin film solar cell and a manufacturing method thereof, wherein the manufacturing method comprises the following steps: providing a hard support plate; forming a stripping layer on the surface of the hard support plate; forming a thin film solar cell layer series on the surface of the stripping layer; forming a flexible support layer on the surface of the thin film solar cell layer series; and separating the flexible support layer and the whole thin film solar cell layer series from the hard support plate. In the invention, the flexible thin film solar cell can be manufactured directly on the surface of the hard support plate such as glass without depending on traditional flexible substrates which are high in requirements for physical and chemical characteristics and high in expense and without the complicated flexible thin film solar cell manufacturing process of firstly adhering the flexible substrate on the surface of the hard support plate and then carrying out thin film deposition, therefore, the method of the invention is a revolutionary method for directly manufacturing a large-area and internal cascade flexible thin film solar cell on the hard support plate.

Description

technical field [0001] The invention relates to the field of photoelectric technology, in particular to a flexible thin-film solar cell and a manufacturing method thereof. 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 ...
