Direction of the electric field inside the photovoltaic cell

Photovoltaic (PV) Cell: Working & Characteristics

At the semiconductor level, the p–n junction creates a depletion region with an electric field in one direction. When a photon with sufficient energy hits the material in the depletion region, the energy from the photon excites a valence electron into the conduction band, leaving a hole in the valence band. Due to the electric field in the

The Direction of the Electric Field By convention, the direction of the electric field is the direction that a positive point charge would move if placed in an area of electric charge. If the positive point charge were placed near a positive charge then the like charges would cause the point charge to move away. The electric
