| 摘要 |
A solar cell and a method for manufacturing the same is disclosed, wherein the solar cell comprises a first cell comprised of a semiconductor wafer with a PN structure; a second cell comprised of a thin film semiconductor layer with a PIN structure, formed on one surface of the first cell; a first electrode layer formed on one surface of the second cell; and a second electrode layer formed on the other surface of the first cell. Unlike the related art solar cell, the solar cell according to the present invention can absorb the light of long-wavelength range in the first cell, and the light of short-wavelength range in the second cell. As a result, it is possible for the solar cell according to the present invention to absorb the light of all ranges, thereby realizing the high efficiency of 20% or above. Also, the entire process time becomes shortened since there is no requirement for the procedure of forming the silicon thin film for a long period of time.
