Journal ArticleDOI
Probing the photoelectrochemical properties of hematite (α-Fe2O3) electrodes using hydrogen peroxide as a hole scavenger
TL;DR: In this article, the fate of photogenerated holes in photoelectrodes for water splitting was examined using H2O2 as an efficient hole scavenger, and all holes that arrived at the electrode/electrolyte interface were collected.
Journal ArticleDOI
High Efficiency Solid-State Sensitized Solar Cell-Based on Submicrometer Rutile TiO2 Nanorod and CH3NH3PbI3 Perovskite Sensitizer
Hui-Seon Kim,Jin-Wook Lee,Natalia Yantara,Pablo P. Boix,Sneha A. Kulkarni,Subodh Mhaisalkar,Michael Grätzel,Nam-Gyu Park +7 more
TL;DR: A continuous drop of voltage with increasing nanorod length correlated with charge generation efficiency rather than recombination kinetics with impedance spectroscopic characterization displaying similar recombination regardless of the nanorods length.
Journal ArticleDOI
Correlation between Photovoltaic Performance and Impedance Spectroscopy of Dye-Sensitized Solar Cells Based on Ionic Liquids
Francisco Fabregat-Santiago,Juan Bisquert,Emilio Palomares,Luis Otero,Dai-Bin Kuang,Shaik M. Zakeeruddin,Michael Grätzel +6 more
TL;DR: In this paper, the characteristics of dye-sensitized solar cells using an ionic liquid as the electrolyte and compare them with the response of a solvent-containing electrolyte cell were analyzed.
Journal ArticleDOI
Structure and Energetics of Water Adsorbed at TiO 2 Anatase \(101\) and \(001\) Surfaces
TL;DR: In this paper, density functional calculations of the (101) and (001) surfaces of the TiO 2 anatase at various coverages have been performed at both low and monolayer coverage.
Journal ArticleDOI
First-Principles Modeling of Mixed Halide Organometal Perovskites for Photovoltaic Applications
TL;DR: In this article, the authors investigate organometal CH3NH3PbX3 and mixed halide CH3 NH 3PbI2X perovskites (X = Cl, Br, I), which are key materials for high efficiency solid-state solar cells.
