A high-efficiency, low-cost large-area multicrystalline silicon solar cell having a cell size of 15 cm*15 cm and a substrate made by the casting method has been developed. The bifacial silicon nitride solar cell (BSNSC) fabrication process was used to construct the cell. By incorporating a new structure at the cell surface, an optimized back-surface field (BSF) process, and an electrode with a ratio of 5.2% into the BSNSC fabrication process, a conversion efficiency of 15.1% (global, AM 1,5, 100 mW cm/sup 2/. 25 degrees C) has been obtained. The uniformity of the electrical performance of the cell has been studied by measuring the distribution of the spectral response at various points on the cell. The results of uniformity testing are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
