Fig. 5: Performance of the ST-OSC powered large-area smart window.
a Schematic illustration of the monolithically integrated ST-OSC–OECD device and its self-powered electrochromic switching mechanism. b J–V characteristics of ST-OSCs with varying Ag electrode thicknesses and MoOX antireflection layers. c Corresponding EQE and transmittance spectra for ST-OSC devices in b. d CIE xy chromaticity coordinates of ST-OSCs: red (10 nm Ag), green (15 nm Ag), blue (15 nm Ag + 30 nm MoOX), and yellow (30 nm Ag). e J–V curve of a large semitransparent module (active area 100 cm2). f Photographs of a scaled model house under three conditions: (i) no device, (ii) ST-OSC only, and (iii) integrated ST-OSC–OECD operating in the colored state.
