NOVELTY - A second electrode material layer is formed covering a photoelectric conversion layer, multiple first electrodes (410) and a transparent electrode. A portion of the second electrode material layer and a portion of the photoelectric conversion layer are removed to form third Y-directional openings that expose the surface of the first electrodes, and second X-directional openings in the first X-directional openings to divide the second electrode material layer into a second comb electrode and a two-dimensional array of multiple second electrodes.    USE - See-through type thin film solar cell module fabrication method.    ADVANTAGE - Increases light transmittance of cell module and prevents short-circuit and current leakage encountered by conventional fabrication method, thus improving production yield and efficiency of solar cell. Includes openings that can expose transparent substrate, thus enabling great improvement in transmittance of cell module.    DETAILED DESCRIPTION - The fabrication method starts with forming a first electrode material layer on a transparent substrate (402). A portion of the first electrode material layer is removed to form first Y-directional openings (406), which divide the first electrode material layer into banding electrode material layers. First X-directional openings (408) are formed intersecting the first Y-directional openings, further dividing the first electrode material layer into a first comb electrode (412) and a two-dimensional array of multiple first electrodes (410). A photoelectric conversion layer is formed covering the transparent substrate, the first electrodes and a portion of the first comb electrode. A portion of the photoelectric conversion layer is removed to form second Y-directional openings parallel to the first Y-directional openings above the first electrodes. An INDEPENDENT CLAIM is included for a thin film solar cell module.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a step in the see-through type thin film solar cell module fabrication method.
