the automated array assembly task, phase 2 of the low cost silicon solar array (lssa) project, is a process development task. this contract includes solar cell module process development activities in the areas of surface preparation, plasma processing, diffusion, cell processing and module fabrication. in addition, a high efficiency cell development activity is included. during this quarter, effort was concentrated on wafer etching for saw damage removal, establishing a standard phosphorous diffusion process and a baseline solar cell process as a test bed, designing a large area square cell including test sites, analyzing module layouts for optimum packing efficiency and fabricating the first tandem junction cells (tjc) for this contract. a tjc with backside contacts gave 15.1 efficiency at am1.
