Abstract:
1. A method of forming emitters for a solar cell, the method comprising: printing a first solid-state dopant source of a first conductivity type above a substrate, the first solid-state dopant source comprising a plurality of spaced apart regions; depositing by chemical vapor deposition a second solid-state dopant source of a second conductivity type above and between the plurality of spaced apart regions of the first solid-state dopant source, wherein the first conductivity type is opposite the second conductivity type; and patterning the second solid-state dopant source to form a plurality of first regions of the second solid-state dopant source alternating with but not in contact with the plurality of spaced apart regions of the first solid-state dopant source, and to form a plurality of second regions of the second solid-state dopant source on the plurality of spaced apart regions of the first solid-state dopant source; and driving dopants from the plurality of first regions of the second solid-state dopant source and from the first solid-state dopant source, but not from the plurality of second regions of the second solid-state dopant source, into the substrate.
