摘要： Disclosed are a solar cell and a method for manufacturing the same. The solar cell comprises asymmetric nanowires each of which has an angled sidewall, and thus incident light can be concentrated at a p-n junction portion by means of a total reflection phenomenon of light caused by the difference between the refractive indices of a semiconductor layer and a transparent electrode layer, and light absorption may increase due to an increase in the light travel distance, thus improving photoelectric efficiency. Further, the method for manufacturing the solar cell involves etching a substrate and integrally forming the substrate and a p-type semiconductor layer including the asymmetric nanowires each of which has the angled sidewalls, thereby enabling reduced manufacturing costs and simple and easy manufacture of the nanowires having the angled sidewalls.
