SOLAR SHINGLE ASSEMBLY EMPLOYING CENTER-CONVERGING FINGERS CONVERGING TOWARD ELECTRODE

摘要

Provided in the present invention is a solar shingle assembly employing center-converging fingers converging toward an electrode. The assembly comprises a main electrode point and fingers provided on a cell shingle. The fingers are arranged in a radial pattern having the main electrode point as a center, such that electrical currents flow from the periphery toward the center and are collected at the main electrode point. The present invention reduces an area of busbar electrodes on a front and back face of a solar cell, thus reducing the amount of silver paste and conductive adhesives. In addition, the number and cross-sectional area of fingers are optimized, thus enabling shingles having such a pattern to have superior photoelectric conversion efficiency compared to conventional cell shingles having parallel fingers.
