Abstract

This invention discloses a preparation method for solar sell groupware, which comprises solar cell, transparent material frame, and transparent adhesive; wherein, arranging and fixing with adhesive the solar cell on bottom of the said frame. Thereby, the surface is covered with superior material frame of high mechanical strength and protection ability, the lighting efficiency is improved greatly, and the invention has low cost and convenient to spread.

Description

technical field [0001] The invention relates to a solar power generation device, in particular to a low-cost, high-efficiency, high-power, large-area solar cell module manufacturing method. Background technique [0002] The basis for the exponential growth in the output and sales of crystalline silicon wafer solar cells in the past two decades is the improvement and development of crystalline silicon wafer solar cell production technology and the continuous reduction of production costs. The known manufacturing method of the solar cell module now consists of a frame, a series group of crystalline silicon wafer solar cells packaged on the frame, and a bypass diode in the junction box. In the packaging process of crystalline silicon wafers vacuum-sealed with resin glue, the welding and packaging of crystalline silicon wafers, such as series and parallel welding and packaging, is a very important process.

Problems solved by technology

In the packaging process of crystalline silicon wafers vacuum-sealed with resin glue, the welding and packaging of crystalline silicon wafers, such as series and parallel welding and packaging, is a very important process. The quality of welding and packaging directly affects the crystalline silicon wafer solar cell components. Reliability, as well as its beautiful appearance, the current conventional method of packaging solar cell modules is mainly to use liquid adhesives for pouring packaging or EVA resin for lamination packaging, and most of them use adhesives - crystalline silicon wafer solar cells - the bottom plate The surface of the crystalline silicon wafer is covered with an adhesive mainly made of epoxy resin. Due to the aging of light, these adhesives will turn yellow in about two years, and the light transmittance will drop significantly.

This type of packaged solar cell module also has problems such as poor mechanical protection performance, pollution prevention and moisture resistance, and its service life and reliability are greatly affected.
