One of the main features of heterojunction silicon solar cells is passivation with a wide-gap semiconductor layer between the ohmic contacts and the active elements of the structure, which creates a high voltage when current flows through it; the voltage must be high enough to reduce the probability of recombination [14, 15].
Generally, heterojunctions have been widely used in the fields of semiconductor electronics and optoelectronic devices in the past period. Besides, chemical vapor deposition (CVD) and mechanical exfoliation are the classic methods for heterojunction preparation.
Meanwhile, synthesis routes, characterization and calculation methods, as well as electrochemical performances of heterostructures are roundly reviewed. Furthermore, prospects and potential directions of heterojunctions are proposed, aiming to guide the future energy storage.
The research of heterojunctions pays more attention to the effects brought by the intrinsic feature of the building blocks (e. g., band structures, alignment styles, semiconductor types, carrier concentration, and Fermi level difference) on the electronic structure and electric field distribution of whole materials.
