Latest Patents

Eric holds a patent for his work on III-V solar cells and doping processes. The patent details zinc diffusion procedures applicable for large-scale manufacture of GaAs and GaSb cells used in tandem solar cells. These cells are designed to achieve high energy conversion efficiency. The patent emphasizes that the zinc doping and carrier concentration must be restricted to less than about 10¹⁹/cm³ to ensure effective light-generated carrier collection, leading to improved short circuit currents. Additionally, the patent outlines methods for confining zinc and arsenic vapors during the heating step, which can be achieved using a proximity source wafer or an encapsulant layer. The zinc diffusion of GaSb is accomplished through a homogeneous light diffusion followed by a patterned heavy diffusion, which facilitates low ohmic contact with the grid lines. Texture etching of the GaSb solar cell is also compatible with this diffusion process.
