A Schematic illustration of electron transport between from Au NPs to POMs by LSPR excitation, and the crystalline structures of Keggin-type PW12, Wells-Dawson-type P2W18 and Preyssler-type P5W30. B I−V curves of PESM based on Keggin-type PW12, Wells-Dawson-type P2W18 and Preyssler-type P5W30 with and without light irradiation, respectively. C Current density of PESM based on Keggin-type PW12, Wells-Dawson-type P2W18 and Preyssler-type P5W30 with and without light irradiation, respectively. Concentration gradient is 10 mM/5000 mM NaCl. D Power density of PESM based on Keggin-type PW12, Wells-Dawson-type P2W18 and Preyssler-type P5W30 with and without light irradiation, respectively. Concentration gradient is 10 mM/5000 mM NaCl. Error bars represent standard deviation of three different measurements. E Comparison of the output power density with previously reported devices. Concentration gradient is 50-fold. Source data are provided as a Source Data file.
