Integration of solar cells and electrochromic windows offers crucial contributions to green buildings. Solar-charging zinc anode-based devices (ZECDs) present opportunities for addressing the intermittency issue. However, limited energy storage capacity ZECDs results in wasted harnessing as well overcharging. Herein, spectral-selective dual-band that continuously transport indoor appliances by remotely controlling repeated bleached-tinted cycles during daytime, are reported.

Abstract Electrochromic devices (ECDs) show promising applications in various fields including energy‐saving smart windows, energy‐recycling batteries/supercapacitors, displays, thermal management, etc. Compared to monovalent cations (H + , Li Na and K ), multivalent‐ion carriers (Mg 2+ Ca Zn Al 3+ ) can enable the ECDs with high optical contrast, capability, attractive long‐term stability because of multiple‐electron transfer redox. Additionally, Mg ‐based assembled metal anodes are exploited for EC electronics, mirrors, flexible devices, Attempts develop be traced 2013. However, since 2017, research activity this field has surged world. Despite fascinating achievements, there is still a long way from their maturity due challenges related limited electrode materials electrolytes, as well obscure redox mechanisms.

Abstract Electrochromic smart windows are promising for building energy savings due to their dynamic regulation of the solar spectrum. Restricted by materials or traditional complementary device configuration, precisely and independently controlling visible (VIS) near‐infrared (NIR) light is still on drawing board. Herein, a novel Zn 2+ electrochemically active Ce 4 W 9 O 33 electrode reported, which demonstrates three distinct states, including VIS NIR transparent “bright warm” state, opaque “dark cool” state. A dual‐operation mode electrochromic platform also presented integrating /NiO anode‐based (Ce /Zn/NiO device). Such enables an added thus realizing four color states through individually NiO electrodes, respectively. These results present effective approach facilitating more intelligent weather/season conditions personal preferences.

The dual-band electrochromic smart windows (DESW) can selectively modulate visible (VIS) and near-infrared (NIR) transmittance, which is expected to effectively reduce building energy consumption. However, the complex preparation of materials has restricted further development DESW. In this work, amorphous crystalline Ti-doped WO3·2H2O (TiWH) were synthesized by a simple precipitation method, does not require strict control oxygen content temperature. Ti doping reduced crystallinity increased specific surface area. 3% TiWH films exhibited excellent electrochromism with high transmittance modulation (633 nm: 83.8%, 1050 72.5%), fast response time (bleached/colored time: 14.9/15.3 s at 633 nm, 16.0/3.5 nm), good coloration efficiency 22.8 cm2 C–1, 90.8 C–1), capacitance 47.1 mF cm–2 0.1 mA cm–2. device still maintain (bright, cool, dark modes). storage make have application prospect in green buildings.

The fusion of electrochromic technology with optical resonant cavities presents an intriguing innovation in the field. However, this is mainly achieved liquid electrolyte-based or sol-gel devices, but not all-solid-state which have broader industrial applications. Here, a new device demonstrated metal-dielectric-metal (MDM) cavity, can achieve strong thin-film interference effects through resonance, enabling to unique structural colors that rarely appeared reported such as yellow green, purple, and light red. color gamut be further expanded due adjustable constants layer.

Electrochromic materials were discovered in the 1960s when scientists observed reversible changes between light and dark states WO3 thin films under different voltages. Since then, researchers have identified various electrochromic material systems, including transition metal oxides, polymer materials, small molecules. However, phenomenon has rarely been non-metallic elemental substances. Herein, we propose development of iodine electrodeposition-based dynamic windows using a water-in-salt electrolyte containing ions. The unique environment solvation structure suppress dissolution shuttle effect iodine, thereby achieving reaction pathway compared to traditional electrolytes. This involves solid-liquid solid solvated iodide window demonstrates high optical contrast 76.0% with near colour neutrality excellent cycling stability. A practical 400 cm2 complementary is fabricated demonstrate good performance, contrast, colour-neutral opaque state, fast response time, uniform modulation, polarity-switchable functionality.
