Development of high-efficiency cascade solar cells. Technical progress report no. 4

Technical Report ·
OSTI ID:6552520
The basic objective of this work is to develop the technology required to fabricate two-junction cascade solar cells having conversion efficiencies of 30 percent or more under multisun illumination. An intermediate objective is to demonstrate a cascade cell having 25 percent conversion efficiency. Experimental cascade cells have previously been demonstrated in two different III-V materials systems: AlGaAsSb/GaAsSb and AlGaAs/GaAs. Although both of these cells were grown by liquid phase epitaxy (LPE), organo-metallic chemical vapor deposition (OM-CVD) growth techniques are also being explored. Progress is reported. (WKH)
