Glass preparation method and photovoltaic glass plate

Abstract

The invention provides a method for preparing hollow microsphere doped glass. The method comprises the following steps: S1, mixing first glass powder, a dispersing agent and a foaming agent into uniform slurry, centrifuging and atomizing the slurry, and drying in a drying oven to obtain a microsphere blank; S2, sintering the microsphere blank to obtain hollow glass microspheres; S3, uniformly mixing second glass powder with the hollow glass microspheres, melting, quenching and annealing to obtain glass doped with the hollow glass microspheres, wherein the melting temperature is lower than themelting temperature of the hollow glass microspheres. Under the condition that the long-afterglow material is added in the S1, the glass doped with the long-afterglow hollow microspheres is obtained.The glass can absorb ultraviolet light to play a role of a light-emitting center and can continuously emit light at night, and when the glass is applied to a photovoltaic module, the photovoltaic module can also be in a working state at night.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a glass doped with long-lasting hollow microbeads excited by ultraviolet light, a preparation method thereof, and a photovoltaic glass plate comprising the glass. Background technique [0002] In response to the increasingly prominent global resource and environmental issues, all countries have begun to attach importance to sustainable development. The radiant power of the sun is about 3.8×10 20 MW, the solar energy received on the ground is about 1.8×10 18 KWh, and the predicted lifetime of the sun is about 4 billion years, so the solar energy is almost infinite. [0003] A solar cell is a photovoltaic system that directly converts solar energy into electricity. However, limited by solar energy resources, solar cells only work normally during the day, and at night, due to the lack of light resources, it is difficult for solar cells to continue to work, which greatly limits the ...
