Abstract :
Large-grain polycrystalline silicon sheets for solar cells, 50 mm square and 0.1 to 0.5 mm thick, have been obtained directly by spinning the silicon melt and diffusing it into mold cavities. Production time from melt is about four sheets per 15 s. Using this sheet, 9 to 10% AM 1.5 solar-cell efficiencies were achieved.
