Silicon heterojunction (SHJ), solar cells based on a heterojunction between semiconductors with different band gaps, are among the most promising photovoltaic technologies. So far, these cells have exhibited remarkable power conversion efficiencies and good operational stabilities.

Despite their great potential and notable advantages, SHJ solar cells are typically based on rare and expensive materials, which limits their widespread deployment. In addition, their fabrication is often incompatible with existing manufacturing processes, further complicating their large-scale production.
