| 20110240113 | SOLAR CELL STRUCTURE - A solar cell structure includes a silicon crystal having at least one slant penetrating hole, the penetrating hole internally having at least one inclined surface; an emitter covering the silicon crystal and the inclined surface in the penetrating hole; and a first metal electrode being electrically connected to the emitter and located in the penetrating hole of the silicon crystal at a bottom thereof. By forming the inclined surface having an inclination angle in the slant penetrating hole, light incident upon the inclined surface of the penetrating hole can have a length-increased optical path in the solar cell to thereby enhance the photocurrent of the solar cell. | 10-06-2011 |
| 20110232741 | SILICON SOLAR CELL - The present invention discloses a silicon solar cell including a silicon crystal, an emitter, a conductive layer, and a first metal electrode. The silicon crystal has at least one through hole formed thereon. The emitter covers at least the silicon crystal and an inner surface of the through hole on the silicon crystal; the conductive layer covers at least a portion of the emitter that is located on the inner surface of the through hole; and the first metal electrode is located in the through hole on the silicon crystal and is electrically connected at least to the conductive layer. | 09-29-2011 |
| 20110168251 | SOLAR CELL MODULE - A solar cell module is disclosed. The solar cell module comprises a first protective layer, a solar cell layer, a sealing material layer and a second protective layer, wherein the sealing material layer is composed of polyurethane formed by reacting an acrylic resin with a curing agent such that the yield of the solar cell module can be improved. Depending upon its practical application, the solar cell module may use the sealing material layer in the absence of the Ethylene Vinyl Acetate (EVA) | 07-14-2011 |
| 20110088767 | Surface structure of crystalline silicon solar cell and manufacturing method thereof - The present invention provides a surface structure of a crystalline silicon solar cell and a manufacturing method thereof. The surface structure of the crystalline silicon solar cell comprises a main body having a front side microstructure and a back side microstructure. A surface morphology of the front side microstructure includes a plurality of cone structures, a surface morphology of the back side microstructure includes a plurality of arc structures, and a surface roughness of the front side microstructure is greater than that of the back side structure. | 04-21-2011 |
