▎ 摘  要

NOVELTY - Processing flexible power-generating glass involves: (1) mixing silicon dioxide, aluminum oxide, graphene, potassium peroxide, boron trioxide and sodium fluoride; (2) melting the mixed materials, continuously flowing molten glass on a molten metal surface, and paving to form a uniform thickness glass ribbon; (3) heating the ribbon, introducing into a tin bath, pulling softened glass ribbon in the bath, and forming the glass ribbon into a glass substrate; (4) preheating the glass substrate; (5) washing the front and back of the substrate with deionized water; and (6) air-drying the glass substrate to obtain a shaped glass plate whose top is provided with herringbone groove, sticking cadmium telluride power generation film at the bottom of the glass plate, embedding the top of the plate with copper strips, contacting film with strips to form an ohmic contact, and absorbing heat source and light source to form current to conduct electricity through strip. USE - The method is useful for processing flexible power-generating glass. ADVANTAGE - The method provides flexible power-generating glass, which has high strength, corrosion resistance and stability. DETAILED DESCRIPTION - Processing flexible power-generating glass involves: (1) evenly mixing various raw materials including 60-70 wt.% silicon dioxide, 10-15 wt.% aluminum oxide, 10-15 wt.% graphene, 5-10 wt.% potassium peroxide, 3-5 wt.% boron trioxide and 2-5 wt.% sodium fluoride in a mixer; (2) melting the mixed raw materials in a melting furnace at high temperature, continuously flowing the molten glass from the furnace on a molten metal surface, paving to form a uniform thickness glass ribbon, cooling, hardening, and separating the ribbon from molten metal; (3) heating the obtained glass ribbon to above softening temperature of 1260-1350 degrees C, introducing the heated glass ribbon into a tin bath, pulling softened glass ribbon in the tin bath with a edge-drawing machine, and forming the glass ribbon into a glass substrate under the action of edge-drawing machine; (4) preheating the glass substrate in a preheating furnace, and introducing the preheated glass substrate into a mixed solution of potassium nitrate and sodium nitrate; (5) conveying the glass substrate into a cleaning line, and washing the front and back of the substrate with deionized water; and (6) air-drying the glass substrate in an air-drying box to obtain a shaped glass plate whose top is provided with herringbone groove, sticking cadmium telluride power generation film at the bottom of the glass plate with a film sticking machine, embedding the top of the glass plate with a copper strip, contacting the film with the strip to form an ohmic contact, and absorbing heat source and light source with the film to form current to conduct electricity through the strip.
