Abstract:
Mist of titanium element-containing liquid particles is adhered to the surface of a glass substrate having a surface compressive stress of at most 10 MPa so as to coat the surface of the glass substrate with the liquid. Next, the liquid-coated surface is heated up to a maximum temperature of from 550 to 700° C. and then cooled under a specific condition, thereby making the resulting glass sheet have a surface compressive stress of from 20 to 250 MPa. The process gives a glass sheet coated with a titanium oxide thin film having a photocatalytic function. The resulting titanium oxide thin filmhad good adhesiveness andabrasion resistance. Since its surface has a micro-roughness, the glass sheet has neither interference color nor interference fringes and has good transparency.

Abstract:
Mist comprising liquid particles containing titanium is adhered to the surface of a glass sheet having a surface compressive stress of 10 MPa or less to coat the surface of the glass sheet with the liquid. The surface coated with the liquid is heated to a maximum temperature of 550 to 700°C, cooled under a specific condition to impart a surface compressive stress of 20 to 250 MPa to the surface. Thus a glass sheet coated with a titanium oxide thin film having a photocatalyst function. The titanium oxide thin film is excellent in adhesion and wear-resistance. Since the surface has a micro roughness, no interference color nor interference fringes are produced, and the transparency is favorable.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a solar cell module, by which the solar cell module can be manufactured by simple operation with good productivity while the solar cell is prevented from cracking. SOLUTION: A laminate body 60 is manufactured by arranging a first sealing resin sheet 20 covering the entire surface of a light receiving surface side transparent board between the light receiving surface side transparent board 2 and solar cells 4, arranging a second sealing resin sheet 30 covering the entire surface of a rear board between the rear board 3 and the solar cells, and arranging sealing sheet pieces 40 to 48 which are thicker than the solar cells at gap parts between the solar cells or at a margin part outside the solar cells. The laminate body is put in a sealing process container composed of a gas impermeable flexible sheet. The plurality of sealing process containers containing the laminate bodies are introduced into an oven and are arranged in parallel at intervals. The inside of the sealing process container is depressurized to exhaust the air between the light receiving surface side transparent board and the rear board. The laminate body is heated to melt the sealing resin by permitting a hot blast to flow parallel to the laminate body in the oven, and then the laminate body is cooled continuously to solidify the sealing resin.
