摘要： Disclosed is a thin film type solar cell which prevents short circuit from occurring between a first electrode and a second electrode due to a burr produced in a separation part, thereby preventing an output from being reduced. The thin film type solar cell includes a substrate, a first electrode disposed over the substrate and being apart from an adjacent first electrode by a first separation part, a semiconductor layer disposed over the first electrode and being apart from an adjacent semiconductor layer by a contact part and a second separation part, and a second electrode disposed over the semiconductor layer and being apart from an adjacent second electrode by the second separation part. The semiconductor layer contacts the substrate through the first separation part, and the second electrode contacts the first electrode through the contact part. A height of a burr produced in the second separation part is lower than a height between the first electrode and the second electrode.
