Electrochromic (EC) smart windows offer high\u2010performance optical modulation but require an external power supply, whereas photochromic (PC) smart windows are self\u2010powered but suffer from low modulation and poor bistability. To bridge this gap, we introduce a novel photo\u2010induced electrochromism (PIEC) mechanism in a proof\u2010of\u2010concept smart window operating with both light and electricity as stimuli. The PIEC device utilizes a sub\u2010stoichiometric WO\n                    <jats:sub>3\u2010x<\/jats:sub>\n                    cathode and a tailored ethylene glycol\u2010based electrolyte, in which photogenerated holes are consumed by the electrolyte, driving Al\n                    <jats:sup>3+<\/jats:sup>\n                    intercalation and coloring the device without an applied voltage.

The performance is further enhanced in the electrically induced coloring state. In a simulated house model, the device reduced indoor temperatures by 7\u00b0C\u201310\u00b0C, and simulations confirmed substantial energy savings of 44% and a reduction in CO\n                    <jats:sub>2<\/jats:sub>\n                    emissions by 88.5\u00a0kg. m\n                    <jats:sup>\u22122<\/jats:sup>\n                    .
