| 摘要 |
The present invention relates to a solar cell having a structure of improved photo-utilization efficiency. The solar cell comprises a transparent texture layer, a transparent conductive layer, a photoelectric conversion layer and a back electrode layer and a substrate under the back electrode layer stacked in a sequence from an incident light side. A laser scribing of module process is performed in the transparent conductive layer, the photoelectric conversion layer and the back electrode layer so as to form a laser scribing region and a photoelectric conversion active region where the transparent texture layer is formed of an angular or arc surface shape and has a concave portion opposite to the laser scribing region. The laser scribing region is provided to guide the incident light to concentrate on the photoelectric conversion active region.
