Double-sided laminated double-glass high-reflective component

Abstract

The invention discloses a double-sided laminated double-glass high-reflective component, comprising the materials arranged in a stacking manner from top to bottom: front glass, a packaging material, alaminated battery string, a packaging material, and rear plate glass, wherein the front glass is anti-reflective film tempered glass or color coated tempered glass; the packaging material is EVA, POE, PVB or organic silica gel; the laminated battery string is arranged by battery pieces; the rear plate glass is grid plated high reflecting layer tempered glass with the thickness of the high reflecting layer of 5 to 200 microns, the back grids of the rear plate glass evenly cover the back of the battery string, the high reflecting layer covers the edge of the battery string at a width of 2-3 mm,the high reflecting layer covers the head of the battery string at a width of 1.5-2.5 mm, the high reflecting layer at the head and tail ends of the battery string extends 2 mm out of the battery pieces, and the side is equivalent to the width of the gap, which is 0-3 mm. The technical solution solves the problem of current mismatch caused by diffuse reflection in the head and tail pieces of thelaminated component string. At the same time, the design of the back glass high reflecting layer can also increase the output of the front power of the component in the case of blocking back battery pieces with equal area.

Description

technical field [0001] The invention relates to a high-power component, in particular to a double-sided laminated double-glass high-reflection component. Background technique [0002] With the market's demand for high-power components and the country's support for high-efficiency components, many manufacturers have made a series of improvements in component materials, component layout design, etc., including MWT, IBC, PERC, black silicon, double-sided cells The application of high-efficiency cells such as wafers, the application of low-yield and high-thickness interconnection strips and high-transparency EVA&POE, and the design of high-efficiency components such as half-cell modules and laminated modules. There are the following defects: [0003] 1. Material application end: limited by the difficulty of technological breakthroughs, mass production and material costs, mass production cannot be achieved; [0004] 2. Module design: In terms of half-cell and stacked-chip desig...
