Heterojunction Solar Panels: How They Work & Benefits
A heterojunction is an interface between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are com

Silicon heterojunction (SHJ) solar cells have enormous application prospects due to their high efficiency and small carbon footprint. However, during long-term use, the i-a-Si passivation layer of heterojunction (SHJ) solar cells tends to be destroyed by ultraviolet radiation, causing performance degradation.
