Latest Patents

Among his latest innovations is a multijunction solar cell featuring a two-step diffusion region in the substrate. This solar cell includes a first subcell with a germanium (Ge) substrate that has a diffusion region doped with n-type dopants, specifically phosphorus and arsenic. The upper portion of this diffusion region has a higher concentration of phosphorus (P) atoms compared to arsenic (As) atoms. Additionally, the second subcell consists of a layer of either gallium arsenide (GaAs) or indium gallium arsenide (InGaAs) placed over the substrate. Another notable patent is a method for fabricating a multijunction solar cell. This method involves providing a substrate and depositing a nucleation first layer directly in contact with it. The process also includes depositing a second layer containing an arsenic dopant over the nucleation layer, which serves as a diffusion barrier to limit the depth of arsenic diffusion into the substrate.
