Abstract:
1. A method for manufacturing a solar cell, comprising: disposing a first electrode on a substrate; patterning the first electrode to form a first groove; disposing a semiconductor layer filling the first groove on the first electrode; patterning the semiconductor layer to form a second groove; disposing a second electrode filling the second groove on the semiconductor layer; patterning the first electrode, the semiconductor layer and the second electrode to form a third groove; and patterning the semiconductor layer and the second electrode to form a fourth groove, wherein the third groove and the fourth groove are alternately arranged along a line that is substantially parallel to the first and second grooves wherein, in a direction perpendicular to the line, the width of the third groove and the fourth groove is less than the width of the first electrode; and wherein, along the line that is substantially parallel to the first and second grooves, a length of the third groove is greater than a length of the fourth groove.
