Photocatalytic organic liquid flow batteries can directly convert solar energy into chemical energy for storage,and have the advantages of both photocatalytic technology and organic liquid flow battery technology.In this paper,a new numerical calculation model for photocatalytic organic liquid flow batteries has been established,which can predict photocurrent and multicomponent transport processes accurately.Based on this model,the effects of electrolyte flow rate and light intensity on the photoelectrochemical properties of photocharged organic liquid flow batteries were studied.The results showed that increasing the electrolyte flow rate could not improve the photoelectrochemical performance of the battery.With the increase of incident light intensity,the charging voltage of the battery also increases,improving the photoelectric conversion performance of the battery to a certain extent.This article can contribute to the application of photocatalytic organic liquid flow batteries.
