Webintrinsic region. This built-in field now tends to pull the mobile electrons back into the N-side. Eventually an equilibrium is established where the current of electrons due to diffusion is equal and opposite the current due to the built-in (internally generated) electric field. The net result is a built-in potential, and zero net current. WebFeb 5, 2024 · The built-in electric field (BEF) intensity of silicon heterojunction solar cells can be easily enhanced by selective doping to obtain high power conversion efficiencies (PCEs), while it is challenging for perovskite solar cells (pero-SCs) because of the difficulty in doping perovskites in a controllable way.
