Abstract

The invention provides a packaged solar cell wafer which comprises a packaging body and the solar cell wafer sealed in the packaging body, and the solar cell wafer is provided with a light inlet face and a shady face. The packaged solar cell wafer is characterized in that the packaging body comprises a packaging inner layer and a packaging outer layer, the packaging inner layer is made from transparent material, and a suede layer is arranged on the surface of the packaging inner layer. Due to the fact that the suede layer is arranged on the surface of the packaging inner layer, the flame light effect of the solar cell wafer can be improved, and therefore the efficiency of a solar cell is improved. Correspondingly, the invention further provides a method for packaging the solar cell wafer. The surface of the packaging body is imprinted through the utilization of a suede mould, or the surface of the packaging body is etched so as to form the suede layer of the packaging body. The manufacturing technology is simple, and meanwhile the antireflection effect and the flame light effect are improved, and the conversion efficiency of the solar cell is enhanced.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a packaged solar cell wafer and a manufacturing method thereof. Background technique [0002] In recent years, due to problems such as energy shortage and environmental pollution, solar energy has become one of the solutions to these problems. With the rapid development of solar cells and semiconductor industries, solar cells are widely used in various fields. [0003] Since the advent of solar cells, improving the conversion efficiency of solar cells has been the goal of technicians working on solar cells. Improving the intrinsic characteristics of solar cells and improving the ability of solar cells to absorb light are two important aspects to improve the conversion efficiency of solar cells. Effectively reducing the reflection loss of sunlight on the surface of silicon wafers is an important method to improve solar energy conversion efficiency. Forming anti-reflection coatings or t...
