Title: Innovations of Timothy D. Dennis in Solar Cell Technology
Introduction
Timothy D. Dennis is an accomplished inventor based in Canton, TX (US), known for his significant contributions to solar cell technology. With a total of two patents to his name, he has made strides in enhancing the efficiency and fabrication processes of solar cells.
Latest Patents
One of his latest patents is titled "Ion implantation of dopants for forming spatially located diffusion regions of solar cells." This invention involves the formation of diffusion regions in solar cells using a blanket layer of film doped with a first conductivity type. Select regions of this film are implanted with dopants of a second conductivity type, allowing for the creation of dopant source regions. The process enables the diffusion of both types of dopants into an underlying silicon material, enhancing the solar cell's performance.
Another notable patent is "Fabrication of solar cells with counter doping prevention." This process includes the printing of dopant sources over a polysilicon layer on the backside of a solar cell substrate. The dopant sources are cured to diffuse into the polysilicon layer, forming diffusion regions while preventing counter doping. This innovation ensures that dopants from one source do not interfere with another, thereby improving the overall efficiency of the solar cells.
