Abstract :
A large-area multicrystalline silicon solar cell with 15 cm×15 cm cell area using a substrate made by a casting method has been developed to obtain high efficiency at low cost. The bifacial silicon nitride solar cell (BSNSC) fabrication process has been applied to this large-area solar cell. By optimizing the surface structure to reduce the reflective losses, the p-n junction formation and the electrode pattern, conversion efficiencies of 15.6% and 15.3% (AM 1.5, global, 100 mW/cm2, 25°C) for large-area multicrystalline silicon solar cells have been obtained by an evaporation method and a screen-printing method, respectively
