Book Description
Available information on liquid phase, vapor phase (including chemical vapor deposition) and molecular beam epitaxy growth procedures that could be used to fabricate single crystal, heteroface, (AlGa) As/GaAs solar cells, for space applications is summarized. A comparison of the basic cost elements of the epitaxy growth processes shows that the current infinite melt LPE process has the lower cost per cell for an annual production rate of 10,000 cells. The metal organic chemical vapor deposition (MO-CVD) process has the potential for low cost production of solar cells but there is currently a significant uncertainty in process yield, i.e., the fraction of active material in the input gas stream that ends up in the cell. Additional work is needed to optimize and document the process parameters for the MO-CVD process. (NTRL site)

Book Description
This report describes a process and structure for the fabrication of high-efficiency GaAs-GaAlAs heteroface solar cells. A GaAs- GaAlAs solar cell with AM1 efficiency greater than 20% has been fabricated on a single-crystal GaAs substrate, and a GaAs-GaAlAs solar cell showing high open-circuit voltage has been fabricated on a single-crystal bulk-Ge substrate.
