notes: label: Description (Brief)
content: Telstar solar cell; "424M42 (3013) repair" and "VI [circled R] Front Stamp" and "[circled R] Front Stamp" penciled on back. #4 of 4 units, each weights 0.8 oz and is made with two assemblies: the cover (sapphire plate brazed into a platinum frame) and the solar cell (silicon cells shingled to provide a series connection and mounted on a ceramic plate). The two units are joined by soldering the cover assembly to the cell assembly along the edges of the ceramic plate. Twelve silicon cell sections are mounted in each module and are designed to be sensitive to the blue-green region of the spectrum. Total initial power of the 3600 cell Telstar array is nominally 14 Watts at 28 Volts. Reference: Bell System Technical Journal 4, part 3 (July 1963), 1765-1816.
