Thin film solar cell with finger pattern

A solar cell structure comprising:

• a substrate with a top surface, an edge, a sidewall and a bottom surface;
• a conductive contact layer with a top surface disposed on the top surface of the substrate,
• an insulator film directly disposed on a region of the top surface of the conductive contact layer;
• an absorber layer disposed on at least another region of the conductive contact layer that is different from the region on which the insulator film is disposed, and wherein the absorber layer is not disposed on the region of the conductive contact layer where the insulator film is disposed;
• a transparent conductive layer disposed on at least the absorber layer;
• and
• a finger pattern including a set of fingers and a busbar, the finger pattern being disposed on the transparent conductive layer, wherein the busbar is aligned substantially over the insulator film so that the busbar is not disposed over the at least another region where the absorber layer is disposed on the conductive contact layer.
