Patent ID: 6864415

Claim:
A photoelectric cell comprising: a first insulating base having on its surface a first electrode layer, said first electrode layer having on its surface a metal oxide semiconductor film on which a photosensitizer is adsorbed, wherein the metal oxide semiconductor film is obtained by implanting ions of at least one gas selected from the group consisting of O 2 , N 2 , H 2 , neon, argon, krypton and other inert gases of Group 0 of the periodic table and thereafter annealing; a second insulating base having on its surface a second electrode layer, said first electrode layer and said second electrode layer arranged opposite to each other; and an electrolyte sealed between the metal oxide semiconductor film and the second electrode layer, wherein: at least one of said first insulating base having an electrode layer and said second insulating base having an electrode layer is transparent; and the metal oxide semiconductor film comprises anatase titanium oxide particles obtained by decomposing peroxotitanic acid.
