Abstract

The invention discloses a film forming method and a method for manufacturing a film solar battery. The film forming method comprises the following steps: providing a substrate; depositing a seeding layer on the surface of the substrate; depositing an amorphous silicon layer on the surface of the seeding layer; and carrying out thermal annealing in high-pressure hydrogen atmosphere so as to convert the amorphous silicon layer into an amorphous silicon layer. The film forming method can form an amorphous silicon film in a simpler and more reliable mode.

Description

technical field [0001] The invention relates to the technical field of photovoltaic solar cells, in particular to a method for forming a thin film and a method for manufacturing a thin film solar cell. Background technique [0002] With the increasing shortage of energy, the development and utilization of renewable green energy has attracted more and more attention, especially the utilization of solar energy has been favored by the world. A photovoltaic device (solar cell) as a solar energy conversion medium converts sunlight, incandescent light, or fluorescence into electrical energy through the photoelectric effect. This transformation is that when light is irradiated on a photovoltaic device, the light energy is absorbed by the active area of ​​the device to generate electron and hole pairs, and then these electrons and holes are separated by the built-in electric field of the device, and the output electric energy is collected by the peripheral circuit. [0003] In rece...
