<p>To provide, in relation to a dye-sensitized solar cell, an inexpensive photovoltaic film material which can solve problems arising from usage of a sensitizing dye comprising an organic substance; and a solar cell having the photovoltaic film. <??>A photovoltaic film 30 comprises photocatalyst-coated particles which include inorganic material particles, titanium dioxide particles coated on the surface of the inorganic material particles, and lithium particles attached to the inorganic material particles and/or the titanium dioxide particles. The photocatalyst-coated particles are obtained by means of: producing a mixture in which an aqueous solution obtained by means of mixing titanium hydroxide gel and aqueous hydrogen peroxide, powder consisting of the inorganic material particles, and water; leaving to stand a second mixture obtained by means of mixing the mixture and lithium chloride aqueous solution, thereby obtaining a product material in which titanium hydroxide is coated on the surface of the inorganic material particles; and thereafter baking the product material. The photocatalyst-coated particles are formed into paste with the use of a binder, and coated onto a conductive glass plate, to thus form a coating. <IMAGE></p> |
