FIGURE 6 PV-EC performance of CO2RR. (A)
Schematic of the PV-EC system. PV-EC device are composed of W@AgD/C on
10 cm2 GDL as cathode, 3-6 silicon cells in series as
modules with a size of 10 cm x 12 cm, Fe-doped Co foam as anode, and
anion exchange membrane. (B) Current density over an applied cell
voltage (green) from the I-V curve and (C) FE toward CO of
photovoltaics-assisted CO2RR system under AM 1.5 G
(orange). Reproduced with the permission.[105]Copyright 2021, Elsevier. (D) Schematic illustration of the PV-EC
device. PV-EC CO2RR system is composed of
Ga0.5In0.5P/GaAs tandem structure as
solar cells, Au25 cluster as cathode part, NiFe inverse
opal as anode, and 3 M KOH as electrolyte. (E) I-V curves of the
Ga0.5In0.5P/GaAs tandem photovoltaics
and Au25-NiFe under AM 1.5G. (F) STC efficiency of
solar-driven CO2RR during 12 h. Reproduced with the

supported on Ni foam were utilized as cathode and anode, respectively,
for PV-EC system with GaInP/GaInAs/Ge solar cell. (H) J-V curves
