Silicon solar energy cell having improved back contact and method forming same
Abstract
A silicon solar energy cell 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 is described. 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.
