Abstract

The invention especially relates to a preparation method of high borosilicate glass for solar photovoltaic batteries. The method comprises the following steps: 1, batch preparation: adding a rare earth element additive to present high borosilicate glass, wherein visible light is formed through converting infrared light and ultraviolet light by a conversion luminescence effect through applying an up-conversion luminescence principle, and illuminates; the rare earth additive is simultaneously used as a clarificant, a color complementation agent and a conversion luminescence couplant to improve the visible light transmittance of glass; and rare earth element borate glass has a high refractive index and a low chromatic dispersion, and is novel optical glass; 2, glass melting: carrying out high temperature melting of the glass batch in an electric melting furnace to form molten glass, carrying out clarification homogenizing, and cooling to form liquid glass; and 3, mechanical shaping: processing the liquid glass through adopting a float process production technology to form flat glass. The glass prepared through the method provided by the invention has a high visible light transmittance, and can be used as a glass matrix material and a packaging material for the solar photovoltaic batteries.
