摘要

In crystalline-silicon solar technology, the barriers to matching thin-film module cost targets are unlikely to be overcome by advances in cell and module process steps alone. Today, the highest material cost for the cell manufacturers is the starting silicon wafer substrate. As a result, extensive efforts are being made to reduce wafer manufacturing costs by driving toward thinner wafers and reducing kerf-loss (silicon waste). This paper introduces a new approach for wafer production that enables a paradigm shift in cost reduction by eliminating kerf-loss. The multiple points of cost reduction achieved by this innovative process will be presented, showing the potential for substantially lowering wafering cost, improving wafer attributes, and providing both upstream and downstream cost savings.
