摘要 |
The present invention relates to a thin film solar cell enabling sunlight to be incident on a light absorbing layer directly without obstacles by forming a buffer layer, a transparent electrode, and a grid electrode on a lower surface of a CIGS instead of forming the buffer layer and the transparent electrode on the upper part of the light absorbing layer as the thin film solar cell used to be manufactured by forming the buffer layer, the transparent electrode, and the grid electrode on the upper part of the conventional light absorbing layer. Also, the solar cell can shorten the distance of an electron-hole moving to the electrode or the buffer layer, wherein the electron-hole is generated by patterning a first electrode and the buffer layer into a shape to mesh with a tooth structure to absorb light energy. |
