## Abstract The performance of __n__‐type back‐contacted back‐junction silicon solar cells where the boron‐doped emitter diffusion on the rear side is locally overcompensated by a phosphorus‐doped base‐type back surface field (BSF) diffusion has been analysed theoretically and experimentally. By ov
