Development of high efficiency (14%) solar cell array module. First quarterly report, November 29, 1978-March 15, 1979
The development of the high efficiency, P/N silicon solar cells has begun. The best efficiency achieved to date on the 3'' diameter cell was 15.6% at AM1 and 28/sup 0/C, slightly below that of 16.5% required for the fabrication of 14% efficiency module. Work is continuing on the cell development, with efforts concentrating on junction formation and back surface field application. The design of the module was completed utilizing 120 3'' diameter cells, Sunadex glass as the superstrate, polyvinyl butyral as the encapsulant, extruded aluminum channel for framing, and Teflon insulated flexible leads as the electrical terminals. The design of the production tooling has been submitted for design review. The tooling consists of: (1) back contact soldering machine, (2) vacuum pickup, (3) anti-reflective coating tooling, and (4) test fixture.
