Abstract

The invention provides a photovoltaic power converter that includes a multilayer structure supported by a substrate having a base layer of a semiconductor material of a first conductivity type and a first emitter layer of a semiconductor material of a second conductivity type opposite said first conductivity type forming a p-n junction region therebetween, and a first current blocking layer of a semiconductor material of the second conductivity type interposed between the substrate and the first multilayer structure. The emitter layer is carbon doped.
