NOVELTY - The crystalline solar cell module has a conductive layer of a tab wire (3) and a finger electrode of a photovoltaic cell (2) are electrically connected through a conductive adhesive (17). The cell is a bus-barless structure without bus-bar electrode. The cell is provided with an electrode for fillet formation (23) which contacts with or spaced apart from a portion of the side surface of tab wire in a connection region where the cell and tab wire are connected with adhesive. The conductive adhesive is configured to form a fillet (17a) in a portion of the side surface of tab wire.    USE - Crystalline solar cell module for converting clean and inexhaustibly supplied sunlight into electricity directly.    ADVANTAGE - As the photovoltaic cell is provided with electrode for fillet formation is contacted with or spaced apart from side surface of tab wire in the connection region and the fillet formed is isolated from conductive adhesive, the adhesive force of the tab wire is improved by attaching through the fillet. Hence the crystalline solar cell module which is excellent in connection reliability and the adhesiveness of tab wire and crystalline photovoltaic cell is achieved. Since the conductive adhesive is used for the connection of the photovoltaic cell and the tab wire, the photovoltaic cell of the bus-bar less structure is connected efficiently by reducing the silver paste for coating the bus-bar electrode. Hence the cost of the photovoltaic cell is reduced. As the bus-bar less structure is used, the collection of electric current is enabled even when the finger electrode is disconnected.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the manufacturing method of the crystalline solar cell module.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic sectional view of the formation state of the fillet in connection region.
