Abstract: A new process of edge sealing for solar cell modules is described. The process comprises coating a waterproof material on the edge of the solar cell module to form a U-like shaped edge sealing which can achieve the function of shock absorber.

Abstract: A photovoltaic panel includes a substrate, a photovoltaic array formed on the substrate; two bus bars formed on the substrate and electrically connected to the photovoltaic array; two interconnecting wires connected to the bus bars; two partially-overlapped first insulation films; a first encapsulating film; a rear substrate; and a junction box disposed on the rear substrate. The first insulation films are located between the interconnecting wires and the photovoltaic array. The first encapsulating film covers the photovoltaic array, the bus bars, the interconnecting wires and the first insulation films. The first encapsulating film has two first slits for allowing the interconnecting wires to pass through. The rear substrate covers the first encapsulating film and has at least one opening for allowing the interconnecting wires to pass through. The interconnecting wires are electrically connected between the junction box and the bus bars to output the current produced by the photovoltaic array.

Abstract: A solar cell module and an edge sealing method thereof are provided. The edge sealing method includes the following steps: providing a solar cell unit, which sequentially has an upper glass substrate, an intermediate and a lower glass substrate; heating and softening glass materials and fill the glass materials fully in a clearances between edges of the upper glass substrate and edges of the lower glass substrate; and cooling down the glass materials, such that the glass materials are formed into one piece with the upper glass substrate and the lower glass substrate and seal the intermediate.

Abstract: A multi-bandgap solar cell is produced by using a transparent intercellular layer to bind two solar cells with different bandgaps. The intercellular layer has at least an adhesive layer.

Abstract: A supporting and cooling structure and a photovoltaic module with the same are described. The supporting and cooling structure includes a supporting frame to fix a photovoltaic panel of the photovoltaic module, and a supporting and cooling member fixed on the supporting frame. The supporting and cooling member touches the photovoltaic panel to further support the photovoltaic panel and to transmit a heat on the photovoltaic panel to the supporting frame therethrough.

Abstract: The present invention provides a junction box configured to be used with a photovoltaic module. The junction box comprises a central connecting portion adapted to receive metallic ribbons extended from the photovoltaic module, and a peripheral portion enclosing the central connecting portion. The peripheral portion comprises a plurality of recesses defined therein, and each of the recesses is adapted to receive a snap ring of a cable. Further, each of the recesses has an opening to the exterior of the junction box, and a channel communicating with the central connection portion. The opening and the channel of the recess define a longitudinal axis extending toward the central connection portion. The junction box of the present invention allows cables to be coupled to the photovoltaic module in multiple directions.

Abstract: A process for making a partially transparent photovoltaic cell or a partially transparent photovoltaic module comprising series-connected or parallel-connected photovoltaic cells comprises the step of forming a patterned back electrode(s) by screen printing, jet printing, roll-to-roll processing or depositing through a shadow mask with openings. The pattern of the back electrode is determined at the same time when the back electrode is disposed, such that the complexity and cost of the process can be reduced.
