| Summary: | In this work, we present a novel artificial photosynthetic paradigm with square meter (m<sup>2</sup>) level scalable production by integrating photovoltaic electrolytic water splitting device and solar heating CO<sub>2</sub> hydrogenation device, successfully achieving the synergy of 1 sun driven 19.4% solar to chemical energy efficiency (STC) for CO production (2.7 times higher than that of large-sized artificial photosynthetic systems) with a low cost (equivalent to 1/7 of reported artificial photosynthetic systems). Furthermore, the outdoor artificial photosynthetic demonstration with <sc>1.268 m<sup>2</sup></sc> of scale exhibits the CO generation amount of <sc>258.4 L</sc> per day, the STC of ~15.5% for CO production in winter, which could recover the cost within 833 sunny days of operation by selling CO. |
