“…The rapid development of highly integrated electronic devices has introduced various functionalizations of electrochromism. One such example is the integration of electrochromism with solar cells, called photoelectrochromism, − where the simultaneous production and storing of energy can widen the way of a next-generation sustainable and integrated energy application field. However, the most highlighted improvements can be found recently in making smart supercapacitors with color-displaying features depending on the state of charge or discharge of the device. , …”

Polymer-based electrochromic supercapacitors (ECSs) are state-of-the-art innovations that use a color change to visually convey stored energy status in real time. However, the electrochemical instability of the polymers utilized in such devices limits their commercialization due to the difficulties in solution processability and short charge–discharge cyclic life. Herein, a simple and cost-effective chemical oxidative polymerization method is proposed for developing a highly stable and electrochromically active nanocomposite comprising poly(o-methoxyaniline) (PMOANI) and WO3 nanoflowers. The nanocomposite shows areal and specific capacitances of 83 mF/cm2 and 133.16 F/g, respectively. Moreover, the practical multifunctionality of the nanocomposite is demonstrated by developing an ECS device (5 × 5 cm2), which shows an energy density of 370 mWh/kg and power density of 4 W/kg with stable and prolonged charge–discharge cycles (>5000). Further, the ECS device is utilized to power a timer display (1.2 V) for >20 min using the energy stored in the charged state (blue color), which changes its color during discharge, demonstrating its capability as a power source with a real-time energy level indicator. It is expected that the polymer/metal oxide nanocomposite will certainly be a promising candidate to replace the traditional polymers in ECS technologies to achieve prolonged stability for their application in modern electronic gadgets and infrastructures.

Although the thermochromic smart windows with adjustable sunlight transmittance to achieve energy savings are gradually improving, they are still difficult to use, limited by their unreasonable thermal response temperature, slow switching time, and poor durability. Here, we demonstrate a dual-function hybrid thermoresponsive smart window device (CPH) by trapping the phase-change polyHEA-HDA polymer (HEA = hydroxyethyl acrylate, HDA = hexadecyl acrylate) and polydopamine@Cs x WO 3 (PDA@ CWO) core−shell nanoparticles within glasses. The introduced PDA@CWO nanoparticles substantially increase the energy transformation efficiency of solar energy to heat due to their outstanding photothermal conversion. When the temperature increases above the phase-transition temperature of polyHEA-HDA polymer, the copolymer components in the composite material undergo a reversible crystalline−amorphous transition, which enables the transformation of the whole smart window from transparency to opaque in a low ambient temperature. The light transmittance in the solar range can be dynamically modulated between 54.8 and 22.9% with a low ambient temperature while maintaining acceptable visible light transparency and effective UV shielding. A model house testing proves an indoor temperature cooling of 7.1 °C. This study offers a new approach to designing an energy-saving smart window system with multifunctionality.

Smart photovoltaic windows (SPWs) are an emerging green technology presenting energy‐saving by combining solar irradiance regulation and solar energy harvesting. The SPWs integrating extraordinary energy‐saving performance, stable and controllable operational mode, and diverse functionality are essential for devising high efficiency energy‐saving buildings (ESBs). However, the attainment of such features has yet to be realized in current iterations of SPWs. Herein, a conceptual demonstration of a split‐type broadband modulation, self‐driven, and self‐cleaning SPWs is presented by coupling a silicon solar cell with a multifunctional chromogenic unit (MCU) for creating highly efficient ESBs. Within the multilayer structured MCU, thermal‐responsive polymer stabilized liquid crystal (PSLC) and VO2@SiO2 nanoparticles act as chromic component, enabling broadband light modulation. Thanks to the excellent electrothermal effect of indium tin oxide (ITO), the phase transition of PSLC and VO2@SiO2 nanoparticles can be induced by the electrical power output generated by the silicon solar cell. Therefore, the transparency of SPWs can be manipulated according to the occupant's preference during the daytime. Moreover, a superhydrophobic SiO2 coating provides SPWs with self‐cleaning capability which effectively reduces water resource consumption and eliminates the inconvenience of window cleaning, while providing occupants with a clear view even in complex weather conditions.
