Abstract
Achieving high current densities without thermal performance degradation at high temperatures is one of the main challenges for enhancing the competitiveness of photo-electrochemical energy storage systems.
Highlights
Practical operation parameters, including daily temperature and redox reaction kinetics, are modeled with respect to heat and charge transfer mechanisms
Our analyses show a profound impact on the resulting solar-to-chemical efficiencies and stored power, which are 21.8% higher than that of a conventional photovoltaic-assisted energy storage system
This paves the way for reassessing the merit of photovoltaic-integrated systems, which have hitherto been underrated as renewable energy storage systems
Summary
Practical operation parameters, including daily temperature and redox reaction kinetics, are modeled with respect to heat and charge transfer mechanisms. We address the thermo-electrochemical behaviour of photo-charging performance for the redox ow cell applications and unravel the synergic effect of the PEC-device-integrated system using a combined model based on our previously veri ed study[12] and heat transfer theory.[15] For effective content delivery, we developed an innovative multi-functional photocharging cell concept (Fig. 1a).
