Abstract:

The objective of this research was to develop the technology required to fabricate two-junction, cascade solar cell assemblies having conversion efficiencies exceeding 25 percent when operating at 25 deg C under 1 sun, AM O conditions. The experimental effort has focused on several different III-V ternary and quaternary materials that show promise for use in fabricating a cascade cell. These include GaA1As, GaInAs, GaInP, GaAsSb, and GaA1AsSb. The work also includes theoretical calculations of cascade solar cell performance over a wide range of operating temperatures. Author
