NOVELTY - A thin film solar cell module comprises photoelectric conversion layers provided on the transparent electrode layer and including first, second, and third photoelectric conversion layers (130, 140, 150). The photoelectric conversion layers further include at least one of a first intermediate layer provided between the first and second photoelectric conversion layers, cut by first cutting grooves, and a second intermediate layer provided between the second and third photoelectric conversion layers, cut by second cutting grooves.    USE - Used as a thin film solar cell module (claimed).    ADVANTAGE - The thin film solar cell module reduces or prevents a lowering of power generation efficiency.    DETAILED DESCRIPTION - A thin film solar cell module comprises a front substrate (110); a transparent electrode layer (120) patterned on the front substrate to have at least first transparent electrodes and second transparent electrodes; photoelectric conversion layers provided on the transparent electrode layer and including at least a first photoelectric conversion layer (130), a second photoelectric conversion layer (140) and a third photoelectric conversion layer (150); and a rear electrode provided on the photoelectric conversion layers. The photoelectric conversion layers further include at least one of a first intermediate layer provided between the first photoelectric conversion layer and the second photoelectric conversion layer, cut by first cutting grooves, and a second intermediate layer provided between the second photoelectric conversion layer and the third photoelectric conversion layer, cut by second cutting grooves. The first intermediate layer and the second intermediate layer are respectively formed of a transparent conductive oxide (TCO).
