It is to provide an essentially transparent solar cell of high efficiency that can be used by accumulating with a display device to generate electricity simultaneously with utilization of the display function, a self-power-supply display device comprising the same, and a process for producing the solar cell. The solar cell comprises at least a transparent conductive substrate having thereon a photoconductor layer that is transparent to a visible ray and has an absorbance of 0.8 or less at a wavelength of from 400 to 800 nm, and a transparent conductive electrode in this order. An embodiment, in which the photoconductor layer contains at least one element selected from Group IIIA elements and at least one element selected from Group VA elements in the Periodic Table, and an embodiment, in which the photoconductor layer contains a metallic oxide semiconductor, are preferred. Furthermore, an embodiment, in which the metallic oxide semiconductor is titanium oxide or zinc oxide, and an embodiment, in which the photoconductor layer has an optical gap of 2.8 eV or more, are preferred.
A solar cell comprising a transparent conductive substrate having thereon a photoconductor layer that is transparent to a visible ray and has an absorbance of 0.8 or less at a wavelength of from 400 to 800 nm, and a transparent conductive electrode in this order.
A process for producing a solar cell comprising a step of providing a photoconductor layer on a transparent conductive substrate by activating a compound containing a nitrogen element to an activated species, and reacting said activated species with an organic metallic compound containing at least one element selected from Al, Ga and In;
