Thin film type solar cell and method for manufacturing the same

A method for manufacturing a thin film type solar cell, comprising:

• forming a plurality of front electrodes at fixed intervals on a substrate;
• forming a semiconductor layer on an entire surface of the substrate including the plurality of front electrodes;
• forming a transparent conductive layer on the semiconductor layer after forming the semiconductor layer;
• forming a plurality of contact portions by removing predetermined portions of the semiconductor layer and the transparent conductive layer;
• printing a plurality of rear electrodes in a pattern having fixed intervals that expose areas of the transparent conductive layer in which separating channels are to be formed, wherein each rear electrode is electrically connected with one of the front electrodes through one of the contact portions, and each rear electrode includes a light-transmitting portion therein so as to enhance a light-transmission area;
• and
• removing the semiconductor layer and the transparent conductive layer from the light-transmitting portions and separating channels by a dry or wet etching process using the rear electrodes as a mask, wherein the transparent conductive layer and the semiconductor layer have a same pattern after the dry or wet etching process.
