Abstract
A photovoltaic cell is provided, which includes: a substrate; a tunnel oxide layer and a doping conductive layer sequentially disposed on a first surface of the substrate in a direction away from the substrate, wherein the tunnel oxide layer includes nitrogen and phosphorus; a doping surface field disposed in the substrate, wherein the doping surface field is in contact with a side of the tunnel oxide layer facing the substrate, the doping surface field includes a doping element of a same conductivity type as a doping element in the substrate, and a doping concentration on a side of the doping surface field facing the tunnel oxide layer is greater than a doping concentration on a side of the doping surface field away from the tunnel oxide layer; and a metal electrode electrically connected to the doping conductive layer.
