Treatment method for improving transmittance of solar super-white rolled glass

Abstract

The invention belongs to the technical field of glass, and proposes a treatment method for improving transmittance of solar super-white rolled glass. By adopting the treatment method for improving transmittance of the solar super-white rolled glass provided by the invention, the solar super-white rolled glass is processed by adopting methods of cleaning, drying, high-temperature heating, stoving, cooling, and cleaning and drying again, so that a Na2SO4 layer is formed at the surface of the solar super-white rolled glass. The transmittance of the glass can be increased by the Na2SO4 layer according to the optical principle, the transmittance of the solar super-white rolled glass at the wave band of 380-1100nm is further improved, and the transfer power of a solar cell system is indirectly improved.

Description

technical field [0001] The invention belongs to the technical field of glass, and in particular relates to a treatment method for improving the transmittance of solar ultra-clear rolled glass. Background technique [0002] In the solar photovoltaic industry, solar ultra-clear rolled glass is one of the encapsulation glass components of the solar cell system. In order to improve the conversion power of the solar cell system, solar ultra-clear rolled glass needs to have high transmittance in the 380-1100nm band. At present, the transmittance of solar ultra-clear rolled glass in this wave band is about 91.3%. [0003] The publication number is CN102219375, and the publication date is October 19, 2011. The patent titled "Solar Ultra-Clear Rolled Glass and Its Preparation Method" discloses the oxide mass percentage of solar ultra-clear rolled glass, and its composition is as follows: SiO 2 72.0%-75.2%, Al 2 o 3 1.0%-2.4%, R 2 O is 13.2%-15.0%, CaO is 8.5%-10.5%, MgO is 0-3.6...

AI Technical Summary
