Lindmayer, J

A silicon solar energy cell is described having a diffusant junction extending inwardly from one surface, an aluminum-silicon junction of the opposite polarity extending inwardly from the other surface, and a film of aluminum-oxygen-diffusant formed over the aluminum-silicon junction. The structure is formed by diffusing an unprotected wafer, coating the diffusant glass so formed on one side of the wafer with aluminum, and heating the wafer.
