Latest Patents
Eric D Jones holds a patent for an InGaAsN/GaAs heterojunction designed for multi-junction solar cells. This patent describes an InGaAsN/GaAs semiconductor p-n heterojunction that is utilized to form a 0.95-1.2 eV bandgap photodetector. This technology is crucial for high-efficiency multi-junction solar cells. The heterojunction is formed by epitaxially growing an n-type indium gallium arsenide nitride (InGaAsN) layer on a gallium arsenide (GaAs) or germanium (Ge) substrate. The InGaAsN layer has a semiconductor alloy composition of In, Ga, As, and N, with specific ranges for x and y. The p-type GaAs layer is lattice-matched to the substrate, allowing for optimal performance. The InGaAsN/GaAs p-n heterojunction can be grown using molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). This innovation provides a high open-circuit voltage of up to 0.62 volts and an internal quantum efficiency exceeding 70%.
