Commercial cells doped with boron are meant for use in low-light applications due to higher efficiencies in lower/diffuse light, and are not very suited to direct-sunlight applications due to the tradeoff. Indium and Gallium-doped single-crystal silicon still wins in efficiency. Phosphorous I have not seen in any of the roughly 5 million cells I've handled as part of QC. I've heard of nanoparticles of phosphorous helping perovskite-based cells, but that's about it. I've never handled one in commercial production.
