abstract = {A major challenge for achieving the energy transition and
transforming the current energy model into distributed
productionis the development of efficient artificial
leaf-type devices capable of directly converting carbon
dioxide (CO2), water andsunlight into sustainable fuels and
chemicals under ambient conditions. These devices should
avoid using critical rawmaterials to be sustainable and
cost-competitive. We report top-level results for the first
time in converting CO2 and H2O tofuels (formate and H2)
using sunlight and electrodes based solely on earth-abundant
materials. The cell provides a solar-tofuelefficiency of> 10
$\%$ combined with world-record current densities to
comparable devices operating at roomtemperature, without
adding sacrificial donors or electrical bias. In addition,
we present the novel concept of producing atthe same time H2
and an H2-storage element (formate), the latter used to
produce H2 when light is absent. This solutionallows
continuous (24h) hydrogen production using an
artificial-leaf device. For the first time, we show the
feasibility of thissolution. The experimental results were
obtained in an optimised, compact electrochemical flow cell,
with electrodes basedon Cu-S and Ni-Fe-Zn oxide (for CO2
reduction and oxygen evolution reaction, respectively)
supported on gas-diffusionsubstrates, integrated with a
low-cost Si-based photovoltaic module. The cell design
allows for easy scale-up and lowmanufacturing and operating
costs. The cell operates at a current density of about 17
mA·cm–2 and a full-cell voltage of 2.5V (stable for at
least ten hours and in on-off operations), providing formate
productivity of 193 mol·h–1·cm–2, paving theway
towards the implementation of affordable artificial-leaf
type systems in the future energy scenario.},
