Nevertheless, it remains challenging to scale despite encouraging demonstrations at low power input. Higher current densities require notable voltage input as ohmic losses and activation overpotentials become more significant, resulting in lower solar\u2010to\u2010CO conversion efficiencies. A concentrated photovoltaic cell is integrated into a custom\u2010made heat managed photo\u2010electrochemical device. The heat is transferred from the photovoltaic module to the zero\u2010gap electrolyzer cell by the stream of anodic reactant and produce synergetic effects on both sides. With solar concentrations up to 450 suns (i.e., 450 kW m \u22122 ) applied for the first time to photo\u2010electrochemical reduction of CO 2 , a partial current for CO production of 4 A is achieved. At optimal conditions, the solar\u2010to\u2010CO conversion efficiency reaches 17% while maintaining a current density of 150 mA cm \u22122 in the electrolyzer and a CO selectivity above 90%, representing an overall 19% solar\u2010to\u2010fuel conversion efficiency. This study represents a first demonstration of photo\u2010electrochemical CO 2 reduction under highly concentrated light, paving the way for resource efficient solar fuel production at high power input.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/aenm.202200585 Authors: Etienne Boutin, Mahendra Patel, Egon Kecsenovity, Silvan Suter, Csaba Jan\u00e1ky, Sophia Haussener Abstract: Abstract Photo\u2010electrochemical production of solar fuels from carbon dioxide, water, and sunlight is an appealing approach.
