“…Also, the structures exhibit long life time due to less electron-hole recombination. HNSs made up of symmetrically arranged interconnected spherical nanoparticles are obtained as a result of these syntheses [57]. These structures are employed as a photoanode material in this article.…”

This chapter covers different routes of preparation of hierarchical nanostructures (HNS) of titanium dioxide. Keeping the interest in developing modern and sustainable methods of materials chemistry, this chapter focuses on synthesis routes for TiO 2 HNSs reported by researchers from all over the world. The chapter includes the details of chemical reactions taking place during the synthesis and the effects of various process parameters like: type of surfactants, organic/inorganic titanium salts, temperature and pressure on products. The obtained TiO 2 HNSs from different synthesis routes are subsequently compared in terms of their morphology, crystallite size, surface area, particle size and phase. The merits and demerits of all synthesis techniques are also added for comprehensive information. At the end, various applications of HNSs are discussed and their performance is analyzed with respect to the morphologies obtained from different synthesis techniques.

“…It is well known that rare-earth (RE) compounds can efficiently convert incident light from either near-infrared or ultraviolet spectral range to visible range owing to their specific 4f electron structure and unique properties. To increase light absorption range of a solar cell, RE compounds are doped in DSSCs acting as either up-conversion [4][5][6][7][8] or down-conversion luminescent medium [3,[9][10][11][12][13][14][15] to extend the spectral-response range of photo-absorber. Numerous studies have demonstrated that introducing dual dopants from RE group (i.e.…”

Luminescence mediums: samarium ion and yttrium ion, were introduced to expand the photo-response region of TiO 2 by means of the down-conversion effect to convert ultraviolet light into visible light, offering a unique method to enhance the photovoltaic performance of dye-sensitized solar cells (DSSCs). Their crystal structures, optical properties as well as photovoltaic performance were investigated systematically. The result indicates that the DSSCs doped with a total molar ratio of 4 mol% of Sm 3+ and Y 3+ show an overall power conversion efficiency of 4.09%, which is equivalent to improvements of 17.52% and 16.2% as compared to the no blocking layer DSSCs and pure TiO 2 blocking layer DSSCs respectively. The improvement in conversion efficiency is attributed to the dual effects including down-conversion of ultraviolet light and reduction of electron-hole recombination rate.

“…Titanium dioxide (TiO 2 ) has received enormous research attention for its wide potential applications in photocatalyst [1e3], photovoltaic [4,5], ultraviolet detector [6,7] and solar cell [8,9] applications, which comes from its excellent properties like chemical stability, high reactivity, nontoxicity and good oxidative characteristics. In its natural form, TiO 2 exists in three kinds of tetragonal phases: anatase, brookite and rutile [10].…”
