Latest Patents

Krygowski holds a patent for an "Arrangement, dopant source, and method for making solar cells." This invention discloses a method that minimizes the handling of cell wafers and involves a single furnace step. The process begins with the creation of dopant sources by depositing selected dopants onto both surfaces of source wafers. The concentration of dopant placed on the surface is relatively low, resulting in what are known as starved sources. These sources are then stacked with photocell wafers in alternating orientations within a furnace. As the temperature is raised, thermal diffusion occurs, allowing the dopant to leave the source wafers and diffuse into the cell wafers, creating the necessary junctions for photocells to operate. The concentration of dopant diffused into a single side of the cell wafer is proportional to the concentration placed on the respective dopant source. Following sufficient diffusion, a layer of oxide is created by introducing oxygen into the furnace environment. Finally, the cell wafers receive an anti-reflective coating and electrical contacts to gather electrical charge.
