Abstract
A thin film type solar cell and a method for manufacturing the same is disclosed, the thin film type solar cell including a front electrode formed on a substrate; a semiconductor layer formed on the front electrode; a transparent conductive layer formed on the semiconductor layer; a rear electrode formed over the transparent conductive layer; and a buffer layer, formed between the transparent conductive layer and the rear electrode, for reducing an electric resistance of the rear electrode and enhancing an adhesive strength between the transparent conductive layer and the rear electrode.
Claims13
A method for manufacturing a thin film type solar cell comprising:
- forming a front electrode on a substrate;
- forming a semiconductor layer on the front electrode;
- forming a transparent conductive layer on the semiconductor layer;
- forming a metal layer on the transparent conductive layer;
- forming a rear electrode on the metal layer, wherein the rear electrode has a oxidization degree lower than the metal layer;
- and
- baking the rear electrode to form an oxide layer of the metal layer between the metal layer and the rear electrode by oxidizing the metal layer during baking the rear electrode.
