Latest Patents
Peter E. Gruenhaum holds a patent for his work on III-V solar cells and doping processes. His patent focuses on zinc diffusion procedures applicable for large-scale manufacture of GaAs and GaSb cells used in tandem solar cells, which are known for their high energy conversion efficiency. The patent outlines that the zinc doping and carrier concentration must be restricted to less than about 1019/cm3 to achieve optimal light-generated carrier collection and, consequently, good short-circuit currents. The amount of zinc available for diffusion during the drive-in heating step is also limited. Furthermore, the confinement of zinc and arsenic vapors during the heating step can be achieved using a proximity source wafer or an encapsulant layer. The zinc diffusion of GaSb is accomplished through homogeneous light diffusion, followed by patterned heavy diffusion to ensure low ohmic contact with the grid lines. Additionally, texture etching of the GaSb solar cell is compatible with this diffusion process.
