Carrier separation in a solar cell usually relies on the p–n junction. Here we show that an n–n type inorganic semiconductor heterojunction is also able to separate the exciton for efficient solar cell applications. The n–n type heterojunction was formed by hydrothermal deposition of Sb 2 (S,Se) 3 and thermal evaporation of Sb 2 Se 3.
They are a hybrid technology, combining aspects of conventional crystalline solar cells with thin-film solar cells. Silicon heterojunction-based solar panels are commercially mass-produced for residential and utility markets.
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.
In 2017, Kaneka Corporation in Japan realized heterojunction back contact (HBC) solar cell with an efficiency of up to 26.7% (JSC of 42.5 mA·cm −2) 25, 26, and recently, LONGi Corporation in China has announced a new record efficiency of 27.30% 16.
Eventually, we report a series of certified power conversion efficiencies of up to 26.81% and fill factors up to 86.59% on industry-grade silicon wafers (274 cm2, M6 size). Improvements in the power conversion efficiency of silicon heterojunction solar cells would consolidate their potential for commercialization.
