“…The Ru‐complex dyes (eg, N719) used in DSSCs have a bandgap of 1.8 eV, therefore, absorbs only in the 300 to 800 nm range, thus half of the incoming solar irradiation in the UV and IR regions remains unutilized. This issue can be resolved by increasing the light absorption in DSSCs using the method of Co‐sensitization of photoanodes …”

A review on spectral converting nanomaterials as a photoanode layer in dye‐sensitized solar cells with implementation in energy storage devices

The present review article aims at the application of rare-earth-based titanium dioxide nanocrystals as spectral converters in photovoltaic devices, with special focus on dye-sensitized solar cells (DSSCs). Additionally, the implementation of DSSCs in energy storage, more importantly, DSSCs and lithium-ion batteries (LIB) integrated devices are systematically described. The absorption in DSSCs is mainly confined to the visible solar spectrum, which is one of the main reasons behind its limited power conversion efficiency. This has led to shifting of research focus on broadening the light absorption range of DSSCs, which can further lead to enhancement in overall power conversion efficiency. TiO 2 , doped with rare-earth (RE) ions, is often used as an electron transport layer (ETL) in DSSCs to overcome this absorption-related issue. This article gives a detailed review of TiO 2 doped with different RE ions, as an electron transport layer in DSSCs. More importantly, we have summarized all the recent important findings with the application of DSSCs in LIB and photocapacitors.

Fiber solar cells as promising wearable power supplies have attracted increasing attentions recently, while further breakthrough on their power conversion efficiency (PCE) and realization of multicolored appearances remain urgent needs particularly in real‐world applications. Here we design a fiber dye‐sensitized solar cell (FDSSC) integrated with a light diffusion layer composed of alumina/polyurethane film on the outmost encapsulating tube and a light conversion layer made from phosphors/TiO2/poly(vinylidene fluoride‐co‐hexafluoropropylene) film on the inner counter electrode. The incident light was diffused to more surfaces of fiber electrodes, then converted on counter electrode and reflected to neighboring photoanode, so the FDSSC efficiently took advantage of the fiber shape for remarkably enhanced light harvesting, producing a record PCE of 13.11%. These efficient FDSSCs also realized color‐tunable appearances, improving their designability and compatibility with textiles. They were further integrated with fiber batteries as power systems, providing a power solution for wearables and emerging smart textiles.This article is protected by copyright. All rights reserved

Synthesis and optimization of photoluminescence properties in potential reddish orange emitting niobate phosphor for photonic device applications

et al. 2021

A series of samarium ions (Sm3+) activated barium sodium niobate (Ba2NaNb5O15) samples have been successfully synthesized via employing a solid‐state reaction technique. Single phase, crystalline tetragonal Ba2NaNb5O15 were formed and the crystallite size of the prepared sample varied with doping of Sm3+ ions. The scanning electron microscopy (SEM) images of Ba2NaNb5O15:Sm3+ illustrate that the particles possess a non‐uniform spherical structure with some agglomeration. The prepared Ba2NaNb5O15:Sm3+ phosphors were efficiently excited with near‐ultraviolet (n‐UV) (406 nm) and emit strong visible emission peaks in the range 550–725 nm. The phenomenon of concentration quenching was detected after x = 0.10 mol of Sm3+ ions concentration for Ba2NaNb5O15, which arises due to non‐radiative energy transfer through dipole–dipole interaction among activator ions. Colour coordinates (0.586, 0.412) for the optimized phosphor lies in the visible reddish orange region. A bi‐exponential decay behaviour was observed for the photoluminescence decay curve of the optimized phosphor sample with an average decay time in milliseconds. The temperature dependent emission intensity confirms that the Ba2−xNaNb5O15:xSm3+ (x = 0.10 mol) phosphor exhibits adequate thermal stability having high value of activation energy (ΔE = 0.201 eV). The comprehensive study and analysis of the as‐prepared samples suggest that the intense reddish orange emitting thermally stable Ba2NaNb5O15:Sm3+ phosphor can act as a potential luminescent material in phosphor coated lighting, solar cells and other photonic devices.
