A similar device has recently also been published for Li–S batteries. (40) To conclude, the family of devices consisting of three electrodes in one enclosure presents a further step toward integration and marks a significant milestone in the solar battery field.
Bifunctional anode heterojunction (BAH) based solar batteries (Figure 3 d) rely on a different light charging mechanism: Upon light absorption, the photoexcited electrons are stored on the bifunctional anode. The hole is then transferred to the cathode via the external circuit.
Operation mechanism of a solar battery. (a) In a solar battery the solar cell functionality can either operate in parallel (IEC) or in series (VEC) to the battery and power supply/consumer (PSU).
By performing both light absorption and charge storage, bifunctional materials enable the most recent and highest level of material integration in solar batteries. To conclude, bifunctional materials are the most recent development in solar battery research.
The first groundbreaking solar battery concept of combined solar energy harvesting and storage was investigated in 1976 by Hodes, Manassen, and Cahen, consisting of a Cd–Se polycrystalline chalcogenide photoanode, capable of light absorption and photogenerated electron transfer to the S 2– /S redox couple in the electrolyte.
In summary, bifunctional electrodes present the next step of integrated solar battery designs. Only two electrodes are required, since one of the electrodes is capable of effectively performing two functions: light absorption and charge storage.
