Array automated assembly. Phase 2. Quarterly report for period ending March 31, 1979

PDF Version Also Available for Download.

Description

Research on the technology readiness of a proposed process sequence for the low-cost fabrication of photovoltaic modules is described. Integration of the process sequence using non-textured 2.125 inch square wafers was initiated during this period. Considerable difficulties were encountered requiring process and material modifications. These include: (1) replacement of N-250 spray-on diffusion source with PX-10 source; and (2) modification of the firing cycles for printed silver and printed aluminum contacts is required to accomodate the change of wafer size and shape. Preliminary results from cells processed through the entire process sequence except laser scribe and spray on AR coating indicate ... continued below

Description

Research on the technology readiness of a proposed process sequence for the low-cost fabrication of photovoltaic modules is described. Integration of the process sequence using non-textured 2.125 inch square wafers was initiated during this period. Considerable difficulties were encountered requiring process and material modifications. These include: (1) replacement of N-250 spray-on diffusion source with PX-10 source; and (2) modification of the firing cycles for printed silver and printed aluminum contacts is required to accomodate the change of wafer size and shape. Preliminary results from cells processed through the entire process sequence except laser scribe and spray on AR coating indicate that the process sequence is feasible. Indicated cell conversion efficiency is 13 to 15%, however, the process at this point is plagued with low shunt resistance and high series resistance in the cells produced.
