Disclosed are a thin film solar cell module and a manufacturing method thereof. The thin film solar cell comprises, from bottom to top, a first substrate, a first electrode, an absorber layer, and a second electrode layer. A current output region with a current output element disposed therein is formed at the thin film solar cell module. The absorber layer in the current output region is removed through a mask, thereby making the first electrode layer contacts directly there with the second electrode layer. The current output region can be formed at the positive electrode, the negative electrode, or both positive electrode and negative electrode simultaneously, of the thin film solar cell module, thereby increasing the contact area between the first electrode layer and the second electrode layer at the positive electrode and the negative electrode. The useless current, the resistance and the heat generated there are reduced.
