FIGURE 8 PV-PEC performance of CO2RR. (A)
Schematic design of the stacked tandem structure of bias-free PV-PEC
system comprising a gold-decorated triple-layer ZnO@ZnTe@CdTe core-shell
nanorod array photocathode,
CH3NH3PbI3 perovskite
solar cell, and Co-Ci anode. (B) Absorption property of two light
absorbers under AM 1.5G. (C) Plots of incident photon-to-current
conversion efficiency (IPCE) of ZCT-Au-PC, Perov SC and Perov SC +
ZCT-Au PC. (D) J-V characteristic of PV-PEC in the stacked tandem
structure composed of ZCT-Au photocathode and Co-Ci anode. (E) Generated
gas production and photocurrent measured by chronoamperometry for 3 h of
bias-free PV-PEC device. (F) FEs toward H2 and CO of the
stacked tandem structure of bias-free PV-PEC device measured for 3 h of
