Advances in Hierarchical Inorganic Nanostructures for Efficient Solar Energy Harvesting Systems

“…Lanthanum-doped up-conversion nanocrystals (UCNs) can convert low-energy infrared photons to high-energy photons. Thus, a ternary photoanode was fabricated by using [187] Copyright © 2019, American Chemical Society), (b) photocurrent density vs potential curve, (c) applied bias to photocurrent efficiency (ABPE) for pristine Fe 2 O 3 and sulfur doped Fe 2 O 3 , (reprinted with permission from [188] Copyright© 2017, American Chemical Society), (d) LSV curves of WO 3 and Ni(OH) 2 /WO 3 electrodes under AM 1.5 G (100 mW/cm 2 ), (reprinted with permission from [189] Copyright© 2020, American Chemical Society), (e) LSV curves for ZnO/Au/g-C 3 N 4 , ZnO/g-C 3 N 4 , ZnO/Au, and ZnO under simulated sunlight and ZnO in dark, (reprinted with permission from [192] Copyright© 2019, Elsevier), (f) PEC characteristics for HiPMS (α-Fe 2 O 3 ), MFS((104)/α-Fe 2 O 3 ) and PS((104) α-Fe 2 O 3 ) under simulated sunlight AM1.5 G, (reprinted with permission from [194] Copyright© 2015, American Chemical Society), (g) LSV curves of TiO 2 , Au/TiO 2 , Tm-UCN/TiO 2 , Tm-UCN/Au/TiO 2, and Au/Tm-UCN/TiO 2 , (reprinted with permission from [195] Copyright© 2019, American Chemical Society), (h) Photocurrent density vs potential curves in dark (dotted line) and light (bold line) for Sample A (833 nm), Sample B (374 nm), and Sample C (123 nm), (reprinted with permission from [243] Copyright© 2016, American Chemical Society), and (i) ABPE curves for different dye sensitized P-25 TiO 2 samples, (reprinted with permission from [200] Copyright© 2016, Elsevier).…”

“…Figure 11(i) shows the ABPE curves for the different dye‐sensitized samples. The sample with (N719+FITC) dyes (fluorescein isothiocyanate, FITC) clicked on P‐25 TiO 2 with a surface coating of cobalt phosphate (Co−Pi) co‐catalyst, (N719+FITC/P‐25 TiO 2 /Co−Pi) showed an ABPE of more than 1 %, which significantly outperformed P‐25 TiO 2 /Co−Pi, because the dye increased the light absorption of P‐25 TiO 2 and led to improved PEC performance [200] …”

(Invited) Engineering Semiconductor Interfaces Via Non-Native Nanostructures to Facilitate Electron-Hole Separation

“…In view of the above constraints among general synthesis approaches of forming heterostructures, we recommend using click chemistry, which has been generalized to a variety of heterostructures of among widely different lattice constants with large lattice mismatch (12,(25)(26)(27). The schematic of click chemistry is provided in Figure 2.…”

“…where, and are number density at trap state and probability of trap state respectively. This trap capacitance (Ctrap) is indicative of either hole transfer from valence band or trapped state and found to be higher than CT. higher the value of lower frequency capacitance the hole transfers from the trapped state, lower the value of lower frequency capacitance, hole transfer from the valance band (25,26). With increase of electron-hole transfer, Rtrapping which denotes the effective trapping and detrapping from conduction and valance band, decreases.…”
