Title: Innovations by Balakrishnan R Bathey in Photovoltaic Technology
Introduction
Balakrishnan R Bathey is an accomplished inventor based in Upper St. Clair, PA (US). He has made significant contributions to the field of photovoltaic technology, holding two patents that showcase his innovative approaches to solar energy production.
Latest Patents
His latest patents include a process for the in-situ diffusion of dopant impurities during dendritic web growth. This invention involves a dendritic web formation process and apparatus designed to diffuse dopant impurities into a growing dendritic crystal web, ultimately producing photovoltaic cells. The solid dopant diffusion source is strategically arranged in a holder mounted in a vertical thermal element, either within the melt furnace or adjacent to the furnace exit port. This setup allows for efficient heating of the solid diffusion source, utilizing thermal conduction from the vertical thermal element. Additionally, auxiliary heater coils can be employed to control the temperature of the solid diffusion source. This innovative method eliminates the need for a separate diffusion gaseous station, streamlining the web growing process.
Another notable patent by Bathey is a method for removing complex oxide film growth on silicon crystals. This method treats thin silicon web crystals used in solar cell production to eliminate complex SiOx contaminants. The process involves immersing a dendritic silicon web with a {111} surface orientation in a caustic solution of KOH or NaOH at a controlled temperature. This treatment effectively removes SiOx contaminants while preserving the integrity of the silicon crystal surface. Following the caustic solution treatment, the web is rinsed in deionized water and may undergo an acid cleaning to ensure any residual contaminants are removed.
