New interconnection technology for enhanced module efficiency

In order to enhance solar modular efficiency, an innovative interconnection method for solar cells has been developed. The solar cells are two-dimensionally interconnected to a large-area, shingle-roof patterned solar cell array. Test samples were fabricated using silicon solar cells with conventional cell structures. Packing densities over 96% and module efficiencies of 17.3% and 13.4% (AM 1.5, 100 mW/cm/sup 2/) were obtained for single-crystalline and polycrystalline silicon solar cells, respectively.<
