Herein, we present a strategy for a switchable electrochromic zinc mirror/battery, which acts as a battery and a switchable electrochromic device via the electrodeposition and dissolution of Zn onto a transparent electrode. In this device, Zn and viologen constitute the anode and the cathode, respectively. Upon battery charging, Zn is electrodeposited onto the electrode to form a mirror while electric energy is stored as chemical energy. If the Zn mirror dissolves, the stored energy is released as electric energy. Compared with traditional electrochemical metallic mirrors, energy is sufficiently and sustainably utilized in this way. Also, a high reflectance of 84.9% and a specific capacity of 65.0 mAh g −1 are obtained for the Zn mirror, suggesting its excellent mirror performance and intrinsic energy storage properties. It is believed that this successful introduction of the battery concept to electrochemical metallic mirrors opens a wide avenue to drive its development toward a more imaginative and environmentally friendly future.

“…The output energy of a PSCs (fiber or film) is entirely dependent on the presence of the photon stimuli. In the absence of the sun light, the relevance of these photo-electric converters ceases to exist [201]. On the other hand, the limited surface of illumination, as mentioned earlier, and the current degradation due to charge trapping in the defective junctions [211][212][213][214] seem to be the unsolvable issues in this area.…”

“…To partially surmount this shortfall, modified highly absorptive perovskite compounds must be formulated specifically to be use in the fiber shape. Additionally, a highly transparent front electrode and an anti-refractive layer (like carbon allotropes) must be accommodated at the top layer [201].…”

Perovskite-based solar cells with high power conversion efficiencies (PCEs) are currently being demonstrated in solid-state device designs. Their elevated performances can possibly be attained with different non-standard geometries, for example, the fiber-shaped perovskite solar cells, in the light of careful design and engineering. Fiber-shaped solar cells are promising in smart textiles energy harvesting towards next-generation electronic applications and devices. They can be made with facile process and at low cost. Recently, fiber-shaped perovskite solar devices have been reported, particularly with the focus on the proof-of-concept in such non-traditional architectures. In this line, there are so many technical aspects which need to be addressed, if these photovoltaic (PV) cells are to be industrialized and produced massively. Herein, a well-organized and comprehensive discussion about the reported devices in this arena is presented. The challenges that need to be addressed, the possible solutions and the probable applications of these PV cells are also discussed. More still, the perovskite fiber-shaped PV cells with other fiber PV devices reported in literature in terms of their scope, characteristic designs, performances, and other technical considerations have been summarised.

Various energy storage devices are highly demanded by o ur modern society. The use of solar energy, an important green energy source, is extremely attractive for future energy storage. Recently, photo‐assisted energy storage devices have rapidly developed as they efficiently convert and store solar energy, while their configurations are simple and their external energy decline is much reduced. Light‐assisted energy storage devices thus provide a potential way to utilize sunlight at a large scale that is both affordable and limitless. Considering rapid development and emerging problems for photo‐assisted energy storage devices, this review starts with the fundamentals of batteries and supercapacitors and follows with the state‐of‐the‐art photo‐assisted energy storage devices where device components, working principles, types, and practical applications are explained. After the detailed demonstration of some photo‐assisted energy storage devices examples, the bottleneck of such light‐assisted energy storage devices is discussed and the prospects of the light‐assisted rechargeable devices are further outlined.
