Journal ArticleDOI
Design and Development of Functionalized Cyclometalated Ruthenium Chromophores for Light-Harvesting Applications
Kiyoshi C. D. Robson,Bryan D. Koivisto,Aswani Yella,Barbora Sporinova,Mohammad Khaja Nazeeruddin,Thomas Baumgartner,Michael Grätzel,Curtis P. Berlinguette +7 more
TL;DR: Electrochemical data indicate that the oxidative behavior of the TPA and metal chelate units can be independently modulated except in cases where the anionic phenyl ring is in direct conjugation with the Tpa unit.
Journal ArticleDOI
Carbon nanotube-based hybrid hole-transporting material and selective contact for high efficiency perovskite solar cells
Kerttu Aitola,Kári Sveinbjörnsson,Juan-Pablo Correa-Baena,Antti Kaskela,Antonio Abate,Ying Tian,Erik M. J. Johansson,Michael Grätzel,Esko I. Kauppinen,Anders Hagfeldt,Anders Hagfeldt,Gerrit Boschloo +11 more
TL;DR: In this paper, a high efficiency perovskite solar cell with a hybrid hole-transporting material counter electrode based on a thin single-walled carbon nanotube (SWCNT) film and a drop-cast 2,2,7,-7,7-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) hole transporting material (HTM) was demonstrated.
Journal ArticleDOI
Novel nanostructures for next generation dye-sensitized solar cells
TL;DR: In this paper, bottom-up self-assembly techniques are developed to fabricate large-area 3D nanostructures that enable enhanced charge extraction and light harvesting through optical scattering or photonic crystal effects to improve photocurrent, photovoltage and fill factor.
Journal ArticleDOI
Chemical Distribution of Multiple Cation (Rb+, Cs+, MA+, and FA+) Perovskite Materials by Photoelectron Spectroscopy
