NOVELTY - The panel has solar cells (10) that includes emitter layer which is positioned at light receiving surface of substrate. The front electrodes (13) are connected to emitter layer and extend parallel in first direction. An interconnector is configured to electrically connect adjacent solar cells and is positioned in second direction crossing front electrodes. The conductive adhesive film is positioned between front electrodes and interconnector. An alignment mark (13a) is configured to indicate bonding location of conductive adhesive film, and positioned on substrate.    USE - Solar cell panel installed in house.    ADVANTAGE - The photoelectric conversion efficiency of the solar cells can be improved. The interconnector can be configured to electrically connect the solar cells to one another. The front and back protective section can be provided to protect the solar cells. The sealing unit is positioned between the front and back protective sections to seal the solar cells. The bowing phenomenon and damage of the substrate can be prevented and reduced more sufficiently and readily when the tabbing process is performed at the low temperature. The back sheet can prevent moisture and oxygen from penetrating into the back surface of the solar cell panel. Thus, the solar cells can be protected from the external environment. The embossed inner surface of the transparent unit is provided to increase the scattering effect of light. The back surface field layer can prevent and reduce the recombination and disappearance of electrons and holes around the back surface of the substrate. Thus, the efficiency of the solar cell can be improved. The resin can contain the reforming material such as silane-based coupling agent, titanate-based coupling agent, and aluminate-based coupling agent, so as to improve the adhesive strength between the front electrodes and the interconnector. The resin can contain the dispersant such as calcium phosphate and calcium carbonate, so as to improve the dispersibility of the conductive particles. The resin can contain rubber component such as acrylic rubber, silicon rubber, and urethane rubber, so as to control the modulus of elasticity of the resin.
