Solar cell, solar cell burning glass and manufacturing method and embossing roller thereof

Abstract

The invention discloses a solar cell burning glass capable of improving output power of the solar cell, a burning glass and solar cell using the burning glass as well as embossing roller for producingthe glass. The whole surface of the burning glass facing the solar cell chip is provided with strip reflecting condensing figure, wherein the depth H of the sunken center part of the strip reflectingcondensing surface is 0.15-0.25mm, the width W of the strip reflecting condensing surface is 0.6-1.2mm, the width Wa of non-condensing surface is 0.1-0.25mm, and the area scale of the strip reflecting condensing surface part in the glass surface facing the solar cell chip is more than or equal to 75%.

Description

Technical field [0001] The invention relates to a kind of glass, in particular to an ultra-white protective reflective condensing glass for solar cells. The invention also relates to a solar cell, in particular to a solar cell with ultra-white protective reflective concentrating glass. The invention also relates to a method for manufacturing glass, in particular to a method for manufacturing ultra-white protective reflective condensing glass for solar cells. The invention also relates to a device for manufacturing glass, in particular to an embossing roller for manufacturing ultra-white protective reflective condensing glass for solar cells. Background technique [0002] In recent years, the price of crude oil has continued to rise rapidly. At the same time, the large-scale exploitation and consumption of conventional energy sources such as petroleum and coal have brought serious impacts on the environment. For this reason, new clean energy has attracted people’s attention. In t...

Problems solved by technology

In this way, the light reflected from the battery chip can be re-reflected and concentrated to the battery chip, and participate in power generation again. This process is repeated countless times, which improves the output power of the solar cell (component). Due to the limitation of production and processing conditions, the area ratio of the reflective concentrating surface 19 in the net-shaped reflective concentrating pattern in the market is currently within 71% of the entire protective glass, and it is difficult to further increase its ratio, which limits the output. With the further increase of power, the production of embossing rollers for ultra-clear protective glass with mesh reflective and concentrating patterns at the same time is difficult and expensive.
