The Low-Cost Silicon Solar Array (LSSA) Project convened its second Project Integration Meeting (the first meeting was called Task Integration Meeting) at the California Institute of Technology campus in Pasadena, California, on April , (An ERDA/JPL in-house review and critique of the previous two-day session was held on April ). The goal of the Silicon Material Task, a part of the FSA Project, was to develop and demonstrate the technology for the low-cost production of silicon of suitable purity to be used as the basic material for the manufacture of terrestrial photovoltaic solar cells. Low cost silicon solar array project, silicon materials task. Establishment of the feasibility of a process capable of low-cost, high-volume production of silane (Step I) and the pyrolysis of.

The resulting Flat-Plate Solar Array (FSA) Project 7 from to , well-funded particularly during the Carter administration, produced several outcomes key to the industry’s recent success. 7 One was a reliable laminated module design incorporating a rugged screen-printed cell, both developed at Spectrolab. 7 The screen-printing approach Cited by: 8.

Part of the development effort of the JPL in-house technology involved in the Flat-Plate Solar Array (FSA) Project was the investigation of a low-cost process to produce semiconductor-grade silicon for terrestrial photovoltaic cell applications. of silane in a fluidized-bed reactor (FBR). Following initial investigations involving 1and 2-in. diameter reactors, a 6-in. diameter, engineering. Even though reports suggest that the silicon share will slowly decrease in the next twenty years, finding a way to manufacture a specific solar grade feedstock in large quantities, at a low cost while maintaining the quality needed, still remains a crucial issue.
