    摘要: A solar cell and a method of manufacturing the solar cell, the solar cell including a first surface configured to receive incident sunlight and having a concavo-convex pattern, a substantially flat second surface opposite to the first surface, a first doped layer formed as a crystalline silicon layer having a first dopant, and a second doped layer formed as an amorphous silicon layer having a second dopant. The processes for forming these layers, with the exception of forming the first doped layer, are performed at a low temperature. Accordingly, reflectivity of sunlight may be minimized, a high terminal voltage may be generated, and a wafer including the solar cell can be kept from being bent.
