Impact of a Mesoporous Titania–Perovskite Interface on the Performance of Hybrid Organic–Inorganic Perovskite Solar Cells

“…19 To improve the performance of mesoscopic solar cells, further investigation is needed to engineer the mp-TiO 2 − perovskite interface. 20,21 In this study, we explored the effect of TiCl 4 post-treatment of mp-TiO 2 on the optical behavior and the level of electronic disorder using the space charge limited current (SCLC) technique and photothermal deflection absorption spectroscopy (PDS) and correlated our findings with the photovoltaic behavior of the fabricated PSC. We further extended the study by investigating the effect of the titania nanoparticle size on the charge transport, recombination properties, optical behavior, and photovoltaic performance of the PSC.…”

“…Among all of them, TiO 2 arguably is the most commonly used ETL has delivered the best photovoltaic performance in PSC thus far 19 . To improve the performance of mesoscopic solar cells, further investigation is needed to engineer the mp-TiO 2 -perovskite interface 20,21 .…”

A facile low temperature route to deposit a TiO2 scattering layer for efficient dye-sensitized solar cells

“…A typical DSC is a sandwich of a nanocrystalline TiO 2 photoanode sensitized with dye molecules and a catalyst--coated counter electrode, with a redox electrolyte in--between. Among conventional metal oxides, TiO 2 and ZnO have been explored extensively in different nanoarchitectures and crystallographic phases [6][7][8][9][10][11] . An optimized photoanode fabricated from multi layers of different sized particles based on anatase TiO 2 have displayed the best performance to date 12 .…”

Efficiency enhancement via tailoring energy level alignment induced by vanadium ion doping in organic/inorganic hybrid solar cells

“…[7][8][9][10][11] Among these, the use of foreign ions embedded into inorganic semiconductor is quite promising, because this offers several merits, such as, the incorporation of foreign ions into inorganic semiconductors can be prepared by a solution-processing and their n-or p-type characteristics dependent on the type of ions, plus the electronic and optical properties of the inorganic semiconductors can be tuned by foreign ions. [12][13][14] Recently, vanadium-based semiconductors have attracted much attention owing to their excellent electronic characteristics originating from the multiple oxidation states of vanadium. [15][16][17] The incorporation of vanadium dopant into titanium dioxide (TiO 2 ) have exhibited intriguing electronic properties such as enhancing surface energy, broadening the absorption band and suppressing the geminate recombination of photoexcited electron-hole pairs, which can improve the photocatalytic activity of TiO 2 effectively.…”
