Integrated Photovoltaic Charging and Energy Storage Systems: Mechanism, Optimization, and Future

Abstract

As an emerging solar energy utilization technology, solar redox batteries (SPRBs) combine the superior advantages of photoelectrochemical (PEC) devices and redox batteries and are considered as alternative candidates for large‐scale solar energy capture, conversion, and storage. In this review, a systematic summary from three aspects, including: dye sensitizers, PEC properties, and photoelectronic integrated systems, based on the characteristics of rechargeable batteries and the advantages of photovoltaic technology, is presented. The matching problem of high‐performance dye sensitizers, strategies to improve the performance of photoelectrode PEC, and the working mechanism and structure design of multienergy photoelectronic integrated devices are mainly introduced and analyzed. In particular, the devices and improvement strategies of high‐performance electrode materials are analyzed from the perspective of different photoelectronic integrated devices (liquid‐based and solid‐state‐based). Finally, future perspectives are provided for further improving the performance of SPRBs. This work will open up new prospects for the development of high‐efficiency photoelectronic integrated batteries.

Advance of Prussian Blue‐Derived Nanohybrids in Energy Storage: Current Status and Perspective

“…[71][72][73] In the structure, the internal reserved space provided by the carbon material can work effectively to mitigate the volume fluctuation and prevent the selenide core of the nanostructure from gathering during the charge-discharge process, which is particularly effective for maintaining the structural integrity of the electrode material. [74][75][76][77] Especially, when the metal-based nanoparticles are in situ coated with the graphitized carbon matrix generated by the organic skeleton, it has a certain role in improving the conductivity and buffer volume changes. In addition, N doping or C doping can promote carrier density, which is conducive to improving conductivity.…”
