Abstract
A process for manufacturing a bifacial photovoltaic cell, comprising the steps: coating a substrate with a boron containing layer; forming a cap layer over the boron containing layer which is on the second surface of the substrate; removing the boron containing layer from the surfaces of the substrate which are not covered with a cap layer; effecting the deposition of a phosphorous containing layer on the surfaces of the substrate which are not covered by the cap layer, and effecting diffusion of the phosphorous and the boron into the substrate; removing the phosphorous containing layer; texturing the substrate where there is no cap layer; effecting the deposition of a phosphorous containing layer on the first surface of the substrate and effecting diffusion of phosphorous into the substrate to form a second n-doped layer; and forming a passivating and/or antireflective coating layer covering the n-doped layer on the substrate's first surface.
