Abstract

Novel methods of producing photovoltaic cells are provided herein, as well as photovoltaic cells produced thereby, and uses thereof. In some embodiments, a method as described herein comprises doping a substrate so as to form a p+ layer on one side and an n+ layer on an another side, removing at least a portion of the n+ layer, and then forming a second n+ layer, such that a concentration of the n-dopant in the second n+ layer is variable throughout a surface of the substrate.
