NOVELTY - A sensitized semiconductor solar cell comprises glass or polyethylene terephthalate first substrate (1); a transparent conductive glass (2) on first substrate; a first anti-reflection layer on another surface of first substrate; an absorption layer (3) made of a light-absorption material on conductive glass; an electrolyte layer (4) on absorption layer; a titanium nitride electrode (5) on electrolyte layer; a glass or polyethylene terephthalate second substrate on electrode; and a second anti-reflection layer on second substrate (1a).    USE - For absorbing light source within a spectrum range from ultraviolet to far infrared.    ADVANTAGE - The sensitized semiconductor solar cell provides good light absorption from ultraviolet to far infrared because light absorption is carried out on two surfaces.    DETAILED DESCRIPTION - A sensitized semiconductor solar cell comprises a first substrate made of glass or polyethylene terephthalate; a transparent conductive layer made of conductive glass on a surface of the first substrate; a first anti-reflection layer on another surface of the first substrate; an absorption layer made of a light-absorption material of TiO2-xNx:In disposed on a surface of the transparent conductive layer; an electrolyte layer on a surface of the absorption layer; a titanium nitride electrode on a surface of the electrolyte layer; a second substrate made of glass or polyethylene terephthalate on a surface of the titanium nitride electrode; and a second anti-reflection layer on a surface of the second substrate. The absorption layer has a wavelength range for absorption during 300-1500 nanometer. The first and second anti-reflection layers are each a silicon quantum-dot film of silicon nitrides (SiNx) that is anti-reflective and light-concentrating.
