“…And sensitizing with dyes: the first works carried out to achieve this objective were based on the adsorption of photosensitive dyes such as erythrosin B and ruthenium polypyridine on TiO 2 lattice (Kamat and Fox 1983;Islam et al 2001). However, the major problem confronting these systems is generally the chemical and thermal instability of the used photosensitive dyes (Al-Attafi et al 2018;Li et al 2019).…”

For many decades, titanium dioxide (TiO 2 ) semiconductor has been extensively applied in several environmental applications due to its higher photocatalytic performances toward different organic pollutants, pharmaceutical compounds, and bacteria. However, its shortfall response to visible light, and the expeditious recombination rate of the photogenerated electron-hole pairs, hampers its utilization. Doping TiO 2 semiconductor with silver nanoparticles is a sound strategy to (1) extend its photocatalytic activity to visible light, (2) prevent the electron/holes pairs recombination due to the formation of the Schottky barrier at the interfaces with TiO 2 that act as an electron-trapping center, and (3) enhance its bactericide performances. This review focuses on the recent progress on silver-doped titanium dioxide (Ag/TiO 2 )-based photocatalysts. It addresses a wide range of Ag/TiO 2 synthesis techniques, their physicochemical properties and discusses thoroughly the important role of silver (Ag) nanoparticles in enhancing the removal capacity and antibacterial performances of the Ag/TiO 2 photocatalysts.

“…Typically, the DSSC photo-anode is prepared by conventional technique i.e. doctor blade but nowadays, many techniques are available which could be applied as per need and device architecture [42][43][44][45][46]. Doping of semiconductor material with suitable cation or anion also alters its optical energy bandgap, and post-deposition treatments like annealing affect the electrical, structural, and other relevant properties [47][48][49].…”

In this era the requirement for energy is enhancing, therefore, many energy resources are developed among them the emerging third-generation dye-sensitized solar cell is one of the environment-friendly solar cell-based technology. Generally, dye-sensitized solar cells consist of a nanomaterial-based photoanode, dye molecules as an absorber, electrolyte, and counter electrode. In the case of indoor application, this solar cell works easily so this is the characteristics of a dye-sensitized solar cell. Moreover, the outdoor performance of DSSC degrades on exposure to sunlight. Exposure to sunlight increases the temperature of the internal component of DSSC and consequently degradation in device performance. Long-term stability is obtained by the choice of such material where degradation takes place slowly and plastic covers are also coated over DSSC to prevent degradation. The solar response of DSSC towards dye was also mentioned, the higher the percentage of EQE higher the efficiency of the device. In this chapter, the authors discuss the introduction of a solar cell, the working principle of DSSC, and the available research background for outdoor performance and long-term stability with a solar response of device i.e. EQE or IPCE.

“…ALD coatings have also been applied to enhance the performance of dye sensitized solar cells (DSC). In a recent work published by Li et al , 132 an ultrathin TiO 2 binding layer was deposited onto TiO 2 host-particles by low temperature ALD, to enhance the interconnection between the host NPs of the photoanode, and to elevate the adhesion between the photoanode and the substrate. With the ALD coating enhanced power conversion was achieved and the ALD TiO 2 coating resulted in lower internal resistance and longer electron lifetime of the cell.…”
