Problems solved by technology

[0002] With the advancement of solar energy utilization and technology, the crystalline silicon adhesive film EVA used in photovoltaic modules is prone to aging under ultraviolet radiation, reducing the adhesion and light transmittance, and shortening its service life.
Due to the low output of crystalline silicon, the high price has largely restricted the development of the solar energy utilization market.

Abstract

The present invention is one kind of white figured glass capable of blocking ultraviolet ray for solar photovoltaic cell assembly with crystalline silicon cell and non-crystalline silicon electrode plates and its production process. The white figured glass is made of material with very low Fe element content and added CeO2, and has very low ultraviolet ray transmittance. Its production process includes sorting material, compounding material, mixing, smelting, rolling, annealing and other steps.

Description

technical field [0001] The invention relates to the ultra-clear embossed glass matched with the crystalline silicon battery and the amorphous silicon electrode plate used in the solar photovoltaic cell module, especially an ultra-clear embossed glass for blocking ultraviolet solar energy and a manufacturing method thereof. Background technique [0002] With the advancement of solar energy utilization and technology, the crystalline silicon adhesive film EVA used in photovoltaic modules is prone to aging under ultraviolet radiation, reducing the adhesion and light transmittance, and shortening its service life. And because the output of crystalline silicon is low, the price is too expensive to a large extent restricting the development of the solar energy utilization market. In order to reduce the cost, many scientific research institutes have used amorphous silicon instead of crystalline silicon as the carrier of photovoltaic cells as the battery board, and it only needs 1 / 3...
