Patent ID: 7982127

Claim:
A thin film solar cell module of see-through type having a plurality of cells connected in series in the X-direction and connected in parallel in the Y-direction, and having a plurality of through holes formed in an opaque substrate among the cells, the thin film solar cell module comprising: the opaque substrate having a plurality of holes, wherein the opaque substrate includes a plastic substrate or a ceramic substrate; a first electrode disposed on the opaque substrate and composed of a plurality of block-like first window electrodes which has a plurality of first scribe windows corresponding to the plurality of holes; a second electrode disposed on the first electrode and composed of a plurality of block-like second window electrodes which has a plurality of second scribe windows corresponding to the plurality of holes and the first scribe windows so as to form the plurality of through holes, wherein the second window electrodes and the first window electrodes are disposed by parallel displacement; and a photoelectric conversion layer disposed between the first electrode and the second electrode, and composed of a plurality of window photoelectric conversion material layers; wherein a top surface and sidewalls of the first electrode around the plurality of holes are covered by the photoelectric conversion layer and not in direct contact with the second electrode, and a top surface and sidewalls of the photoelectric conversion layer around the plurality of holes are covered by the second electrode, and the second electrode and the photoelectric conversion layer do not extend over sidewalls of the plurality of holes in the opaque substrate.
