| 20100193022 | SOLAR CELL AND METHOD OF MANUFACTURING THE SAME - Provided are a solar cell and a method of manufacturing the same. The solar cell includes a transparent substrate. A first electrode and a transparent insulating layer are sequentially stacked over a plurality of first regions of the transparent substrate. A first electrode, a light-converting layer, a transparent insulating layer, and a second electrode are sequentially stacked over a second region of the transparent substrate other than the first regions. Therefore, light incident from the substrate can penetrate between the light-converting layers spaced apart from each other, thus manufacturing a transparent solar cell. Also, since light scattered by the transparent insulating layer is also incident into the side of the light-converting layer, the light-receiving area is not reduced and thus the efficiency of the solar cell can be increased. | 08-05-2010 |
