Latest Patents
Among his latest patents, Guo has developed innovative photovoltaic devices featuring textured transparent conductive oxide (TCO) layers. One of his notable inventions outlines a method for sputtering a TCO material onto a substrate, which results in a textured topography at the interfaces of various layers. This textured topography can achieve an average roughness ranging from about 5 to about 40 nm. The process conditions for this method include providing oxygen in the sputtering environment at a flow rate of up to 30 sccm, heating the substrate to at least 200 degrees, or increasing the magnetic field strength above 40 mT. The resulting textured topography creates interfacial transition areas that exhibit hybrid physical properties compared to their constituent materials. Another significant patent involves a photovoltaic device that includes a protective layer situated between a window layer and an absorber layer. This protective layer prevents the dissolving or intermixing of the window layer into the absorber layer during the device activation step, along with methods for manufacturing such photovoltaic devices.
