Journal ArticleDOI
Photoelectrochemistry of polycrystalline n-wo3: Electrochemical characterization and photoassisted oxidation processes
Jean Desilvestro,Michael Grätzel +1 more
TL;DR: In this article, the influence of pH, the nature of the electron donor, and RuO 2 or Au overlayers on the photocurrentpotential curves of polycrystalline n-WO 3 electrodes is presented.
Journal ArticleDOI
Unraveling the Impact of Rubidium Incorporation on the Transport-Recombination Mechanisms in Highly Efficient Perovskite Solar Cells by Small-Perturbation Techniques
Abdulrahman M. Albadri,Pankaj Yadav,Mohammad Hayal Alotaibi,Neha Arora,Ahmed Y. Alyamani,Hamad Albrithen,Hamad Albrithen,M. Ibrahim Dar,Shaik M. Zakeeruddin,Michael Grätzel +9 more
TL;DR: In this article, the effect of Rubidium incorporation into lead halide perovskite films on the photovoltaic parameters of PSCs was explored using intensity-modulated photocurrent spectroscopy (IMPS).
Journal ArticleDOI
Anisotropic photocatalytic properties of hematite
TL;DR: In this paper, the flatband potential of a single crystal is -0.02 to 0.03 V more negative for crystal faces than for crystal edges, and the transition from falling to rising transients occurs at a more positive potential for edges than for faces, consistent with more rapid charge transport away from edge surfaces.
Journal ArticleDOI
Near-IR photoresponse of ruthenium dipyrrinate terpyridine sensitizers in the dye-sensitized solar cells.
Guocan Li,Aswani Yella,Douglas G. Brown,Serge I. Gorelsky,Mohammad Khaja Nazeeruddin,Michael Grätzel,Curtis P. Berlinguette,Michael Shatruk +7 more
TL;DR: These complexes afford a photoaction spectral response at wavelengths of up to 950 nm, one of the most red-shifted values reported to date for molecular dyes in the dye-sensitized solar cell (DSSC).
Journal ArticleDOI
Charge carrier chemistry in methylammonium lead iodide
Alessandro Senocrate,Alessandro Senocrate,Tae-Youl Yang,Giuliano Gregori,Gee Yeong Kim,Michael Grätzel,Michael Grätzel,Joachim Maier +7 more
TL;DR: In this paper, the point defect chemistry of methylammonium lead iodide perovskite solar cells is investigated and the decisive carriers are identified and their concentrations discussed as a function of stoichiometry and dopant content.
