Research on high-efficiency, single-junction, monolithic, thin-film a-Si solar cells. Annual subcontract progress report, 1 February 1984-31 January 1985
This research program consisted of five tasks. Task 1, Amorphous Silicon Materials Research, involved producing and optimizing amorphous silicon material. Task 2, Non-Semiconductor Materials Research, involved producing nonsemiconductor materials required to make high-performance, amorphous silicon solar cells. Task 3, Solar Cell Research, involved fabricating and characterizing high-efficiency, single-junction, p-i-n amorphous silicon solar cells. In Task 4, Monolithic, Intra-Connected Cells/Submodule Research, research and development was performed to produce submodules of monolithic, intraconnected solar cells. In Task 5, Multi-Chamber Deposition System, a multi-chamber system was designed to fabricate submodules of at least 1000 cm/sup 2/. The major goals of the program are: (1) to obtain a conversion efficiency of at least 12% (AM1) in a single-junction, p-i-n, 1-cm/sup 2/ solar cell; (2) to eliminate the deleterious effects of light-induced, metastable centers; (3) to operate a multi-chamber deposition a-Si growth system; and (4) to demonstrate a stable submodule with an 8% conversion efficiency (AM1) and a total area of at least 1000 cm/sup 2/.
