The less Auger recombination of heterojunction batteries is due to its special structural design and material selection, which effectively inhibits the occurrence of Auger recombination and improves the efficiency and stability of the batteries.

In heterojunction batteries, electrons and holes are easier to separate and transport at the heterojunction interface because of the different energy gaps between the two semiconductor materials. In addition, heterojunction cells usually adopt thin film structure, which reduces the diffusion length of carriers and further reduces the possibility of Auger recombination.
