<p>PROBLEM TO BE SOLVED: To provide an insulating substrate for a thin-film polycrystal silicon solar battery, capable of improving the efficiency of photoelectric exchange by forming a texture structure on the surface of a silicone-based resin layer, and having excellent flexibility and heat resistance. SOLUTION: This insulating substrate for the thin-film polycrystal silicon solar battery is obtained by forming the silicone-based resin layer obtained by compounding 5-30 wt.% inorganic filler having 3-300 nm average particle diameter with a silicone-based resin obtained by adding an alkyl group, an alkenyl group, a phenyl group or the like as a side chain to a main skeleton consisting of Si-O-Si bond, on the surface of a metal substrate, and has the surface roughness of the silicone-based resin layer regulated so that the Rmax may be 0.3-1.5μm. Silica, titanium oxide, alumina or the like is used as the inorganic filler.</p> |
