      abstract     = {Progress in the development of CO2 reductioncatalysts has
                      revealed more stable and selective options for solarfuel
                      production. In most cases, the catalysts are tested under
                      steady-state conditions. However, to become a reliable
                      long-term storagesolution for renewable energy, particularly
                      photovoltaics (PV), CO2electroreduction must tolerate power
                      intermittency. Directcoupling of CO2 electrolyzers to PV
                      devices enables carbonutilization and efficient energy
                      storage but requires catalysts thatmaintain consistent
                      performance under dynamic power input.Herein, we select an
                      Ag nanoparticle gas diffusion cathode withstable CO
                      production across a wide current density range. Thesystem,
                      directly coupled to a hardware-emulated Si-PV
                      moduleoperating under a realistic sunny day profile,
                      achieves $96\%$ energy coupling efficiency and reaches a
                      cumulative solar-to-chemical(CO) efficiency of $8.8\%$ in 1
                      day. This study demonstrates the potential of Ag-based
                      cathodes for robust performance in variable PV-powered
                      systems and introduces a novel test methodology that better
                      reflects real-world PV-electrolyzer integration,
