Then, the impact of the heterojunction structure on the performance of solar flow batteries was investigate in this study. The experimental findings reveal that the formation of the heterojunction structure effectively mitigates the recombination rate of photogenerated carriers within the photoelectrode.
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.
The formation of this heterojunction structure aims at broadening the solar absorption spectrum of the independent Fe 2 O 3 photoelectrode, negatively shifting the flat band potential of the photoelectrode, reducing the recombination rate of photogenerated electrons/holes.
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.
