Abstract: PROBLEM TO BE SOLVED: To provide a dye sensitized solar battery containing titano-silicalite-2. SOLUTION: A solar battery comprises a semiconductor electrode 10 formed by coating a mixture layer of transition metal oxide and titano-silicalite-2 on a transparent base plate 12, an opposing electrode 20, and electrolyte liquid 30 filled between the semiconductor electrode 10 and the opposing electrode 20. It is preferable that the semiconductor electrode includes a layer of dyestuff molecule like ruthenium complex absorbed to the transition metal oxide. Nano- particle of titanium dioxide is preferable as the transition metal oxide. It is preferable for the mixture layer to have a thickness of 10-30 μm.

Abstract: PROBLEM TO BE SOLVED: To provide a dye sensitized solar battery capable of improving a long-term stability against external factors such as temperature-rises of a solar battery due to a direct sun exposure, without reduction of photo-conversion efficiency. SOLUTION: An electroconductive transparent circuit board 12 and a transition metal oxide layer 14 composed of nano-particle titanium dioxide coated on this electroconductive transparent circuit board 12 constitute a semiconductor electrode 10, whereas an electroconductive transparent circuit board 22 and a platinum layer 24 coated on this electroconductive transparent circuit board 22 constitute the counter electrode 20. Then, between these electrodes (10, 20), a gel type polyelectrolyte 30 composed of polyvinylidene fluoride (PVDF) polymer or N-methyl-2-pyrrolidone (NMP) solvent or 3-methoxy propionitrile (MP) solvent containing 3 to 20 wt.% of its copolymer is installed.
