Heterojunction solar cells (HJT), variously known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT), are a family of photovoltaic cell technologies based on a heterojunction formed between semiconductors with dissimilar band gaps. They are a hybrid technology, combining aspects of conventional crystalline solar cells with thin-film solar cells.
At 26.81%, the efficiency figure achieved in Nov. 2022 is the highest reported so far for a crystalline silicon solar cell with an HJT-only cell structure.
