| Abstract(in English) | For the purpose of the realization of thin-type crystal silicon solar cells, a light trapping effect in a light absorption layer is important, and forming a texture structure for the purpose of multiple reflection of light is necessary. Our group put focus on the nanoimprinting method as the texture forming method. In this report, the absorption rate by optical simulation was evaluated for the combination of the surface and rear texture alone and the combination of the surface / rear texture. As a result, the combination of surface-rear texture with the micron scale tended to increase the absorption rate compared with single side texture. In addition, from the light absorption distribution, spots region that strongly absorb light in the medium and long wavelength region were confirmed. From these results, it is considered that the combination of surface/ rear texture on the micron scale is effective for the light trapping structure of thin-type crystal silicon solar cells. |
