Problems solved by technology

[0007] Although reducing the thickness of the silicon substrate can reduce the manufacturing cost, however, if the thickness is too thin, it is easy to produce bending deformation, and the degree of deformation will expand the degree of warpage as the size increases
However, there is no effective way to solve the above problems

Abstract

The invention discloses a process for thinning solar cells, which can reduce the manufacturing cost of solar cells. The invention particularly relates to a process for preparing films on a solar cell substrate by applying the sputtering technique, and employs the sputtering technique to form a buffer layer on the solar cell substrate to reduce or remove the stress thereof.

Description

technical field [0001] The invention relates to a manufacturing process of solar cells, in particular to a method for manufacturing thinned solar cells. Background technique [0002] In recent years, based on the rapid development of industry, the fossil energy on the earth has been depleted rapidly, and environmental pollution has become increasingly serious. Therefore, all countries in the world are committed to developing alternative energy based on energy demand and environmental protection pressure. Solar energy is the most abundant resource available to human beings today, and it has the advantages of no transportation cost, clean and environmentally friendly, and no heat load on the earth. Based on the above advantages, solar energy is one of the clean and renewable energy sources with the most development potential. [0003] A solar cell is a semiconductor component that uses the photovoltaic effect to convert sunlight energy into electrical energy. Basically any ...
