Patent

CA 1114050

ABSTRACT OF THE DISCLOSURE: The invention provides a method of producing solar cells having a composite shallow/deep junction device construction. The solar cells have grid-like contacts on their front energy-receiving sides, with each portion of each contact being coincident, i.e., aligned with, the deep junction regions while the shallow junction regions are exposed to incident radiation. The composite junction and contacts are formed by a novel method which employs conventional techniques, notably the use of doped oxide films as diffusion sources.
