Abstract
A solar cell includes a first conductivity-type semiconductor layer, a second conductivity-type semiconductor layer, a first electrode, and a second electrode. The first conductivity-type semiconductor layer has a front side intended to serve as a light-receiving surface. The second conductivity-type semiconductor layer is disposed on a back side of the first conductivity-type semiconductor layer, forming a p-n junction together with the first conductivity-type semiconductor layer. The first electrode passes through the second conductivity-type semiconductor layer toward the first conductivity-type semiconductor layer with a tip extending into and ending within the first conductivity-type semiconductor layer. The second electrode is disposed at a back side of the solar cell.
