Research on High-Efficiency, Multi-GAP, Multijunction, Amorphous-Silicon-Based Alloy Thin-Film Solar Cells: Phase 1 Semiannual Subcontract Report, 1 March 1987--31 August 1987.

摘要

The research program described in this report is directed toward advancing our understanding of amorphous-silicon-based alloys and their use in small-area multijunction solar cells. Its principal objectives are (1) to develop a broad scientific base for the chemical, structural, optical, and electronic properties of a-Si based alloys; (2) to determine the optimum properties of alloys materials as they relate to high-efficiency cells; (3) to determine the optimum device configuration for multijunction cells; and (4) to demonstrate a proof-of-concept multijunction a-Si alloy-based solar cell having an efficiency of 18% under standard AM1.5 global insolation conditions and having an area of at least 1 cm sup 2 . This semiannual report describes some of the research results obtained in Phase I. 20 refs., 37 figs., 10 tabs. (ERA citation 14:012770)
