Abstract:
1. A photoelectric conversion element comprising a solar-energy layer including an N-type semiconductor layer and a P-type semiconductor layer stacked together top down or bottom up, said P-type semiconductor layer being doped on a surface of said N-type semiconductor layer; a bond layer stacked on said solar-energy layer and having a plurality of holes allowing light to pass, including an indium tin oxide layer, a silver layer, a titanium layer, a platinum layer, a gold layer, an indium layer, a gold layer and a titanium layer stacked sequentially; and a LED (Light Emitting Diode) layer stacked on one side of said bond layer opposed to said solar-energy layer and including an electron supply layer, a hole supply layer and an active layer; wherein said indium tin oxide layer directly contacts said LED layer, and said titanium layer directly contacts said solar-energy layer, said holes completely extending through said layers of said bond layer between said solar-energy layer and said LED layer, and said P-type semiconductor layer being located directly under said holes to receive the light passing through said holes.
