“…[1][2][3][4][5] They are recognized as a suitable "green" nanotechnology, because do not impede visibility as other conventional blinding systems, providing, at the same time, glare control, thermal, and visual comfort management. Electrochromic (EC) smart windows, or dynamic tintable glazings, belong to the promising category of products changing their light transmittance in response to external stimuli, like electric field or sunlight irradiance.…”

Electrochromic devices (ECDs) represent one of the most promising energy saving and solar control technology for the market of energy‐efficient building and optoelectronic devices. A continuous and intense effort is currently devoted to the development of effective solid‐state ECDs and their integration in multifunctional systems, such as photoelectrochromics. Here, the fabrication of simplified all‐solid‐state WO3 based ECDs on single‐substrate is reported, demonstrating how the rational design of highly interconnected WO3 columnar nanostructures with Nafion polymer matrix remarkably decreases the charge transport barrier at the hybrid electrolyte/electrochromic interface (EEI), thus determining an impressive improvement of overall device performances. The soft polymer substrate of the electrolyte plays a key role on the formation of WO3 pillar‐like structures and on the increase of interfacial contact area by affecting the vacuum‐deposition WO3 growth. Apart from providing higher transmittance in bleached state, the resulting device, entirely manufactured at room temperature by bottom‐up process, exhibits lower activation voltages (0.5–3 V) and faster switching kinetics (5–10 s) compared with monolithic ECDs based on both bulk and mesoporous WO3 films. Furthermore, the enhanced EEI enables the scale‐up on large area and flexible substrate ensuring simultaneously a wide optical contrast (ΔT = 70%), and high coloration efficiency.

Exploring prospective materials for energy production and storage is one of the biggest challenges in this century. Solar energy is arguably the most important amongst various renewable energy resources, due to its wide availability and sustainability with lowest environmental impact. Metal halide perovskites have emerged as a class of semiconductor materials with unique properties including tuneable band gap, high absorption coefficient, broad absorption spectrum, high charge carrier mobility and long charge diffusion lengths, which enable a broad range of photovoltaic and optoelectronic applications. Since the first embodiment of perovskite solar cells showing a power conversion efficiency of 3.8%, the device performance has now been boosted up to a certified 21% within a few years. In this perspective, we summarize differing forms of perovskite materials produced via various deposition procedures, focusing on their energy related applications, and discuss current challenges and possible solutions, with the aim of stimulating potential new applications.

“…For selfpowered system of smart windows, a proof-of-concept experiment involving an integrated color-changing system consisting of solar cells and electrochromic devices has been designed and demonstrated [28]. Recently, Cannavale et al reported a perovskite-based photovoltachromic device with self-adaptive transparency [29], which is capable of producing electrical power by solar energy conversion as well as undergoing an electrochromic transition from neutral-color semi-transparent to dark blue-tinted when irradiated by solar light, without any additional external bias. The result represented a significant step toward the commercialization of smart windows for buildings or transportation tools.…”

Energy storage devices with the smart function of changing color can be obtained by incorporating electrochromic materials into battery or supercapacitor electrodes. In this review, we explain the working principles of supercapacitors, batteries, and electrochromic devices. In addition, we discuss the material candidates for electrochromic energy storages in detail. The challenges of the integrated electrochromic energy system for simultaneous realization of electrochromism and energy storage are specially highlighted.
