RESEARCH ON THIN FILM POLYCRYSTALLINE SOLAR CELLS.
Abstract
Large-area (56 sq cm) cells that were 4.6% efficient and a solar panel - 1/2 sq ft in area - were fabricated. On the average, the efficiency, the power output per unit weight, and the yield of large area solar cells made from cadmium telluride films all increased monotonically during the contract period (1 September 1962 to 31 December 1964). The composite objective for the run of the contract was the development of lightweight, flexible, solar cells of approximately 5% maximum efficiency. The semiconductor material was to be polycrystalline cadmium telluride. The cells were to withstand, or show promise of withstanding, without deterioration a normal laboratory environment, particle and ultra-violet radiation, high and low temperatures, and vacuum. The various investigations that were undertaken to achieve such large area cells are discussed in detail in this report. The investigations include studies of photovoltaic junctions, film growth techniques, collector electrodes, collector busbars, and capsulation techniques. (Author)
