Aswani Yella,Hsuan-Wei Lee,Hoi Nok Tsao,Chenyi Yi,Aravind Kumar Chandiran,Md. K. Nazeeruddin,Eric Wei-Guang Diau,Chen-Yu Yeh,Shaik M. Zakeeruddin,Michael Grätzel +9 more
TL;DR: In this article, a Co(II/III)tris(bipyridyl)-based redox electrolyte was used in conjunction with a custom synthesized donor-π-bridge-acceptor zinc porphyrin dye as sensitizer (designated YD2-o-C8).
Journal Article
Porphyrin-sensitized solar cells with cobalt (II/III)-based redox electrolyte exceed 12 percent efficiency (vol 334, pg 629, 2011)
TL;DR: Mesoscopic solar cells that incorporate a Co(II/III)tris(bipyridyl)–based redox electrolyte in conjunction with a custom synthesized donor-π-bridge-acceptor zinc porphyrin dye as sensitizer are reported, enabling attainment of strikingly high photovoltages approaching 1 volt.
Journal ArticleDOI
Dye-sensitized solar cells with 13% efficiency achieved through the molecular engineering of porphyrin sensitizers
Simon Mathew,Aswani Yella,Peng Gao,Robin Humphry-Baker,Basile F. E. Curchod,Negar Ashari-Astani,Ivano Tavernelli,Ursula Rothlisberger,Md. K. Nazeeruddin,Michael Grätzel +9 more
TL;DR: A molecularly engineered porphyrin dye is reported, coded SM315, which features the prototypical structure of a donor-π-bridge-acceptor and both maximizes electrolyte compatibility and improves light-harvesting properties.
Journal ArticleDOI
Perovskite solar cells employing organic charge-transport layers
Olga Malinkiewicz,Aswani Yella,Yong Hui Lee,Guillermo Mínguez Espallargas,Michael Graetzel,Mohammad Khaja Nazeeruddin,Henk J. Bolink +6 more
TL;DR: In this article, a perovskite solar cell was fabricated by using room-temperature deposition processes and the cells were based on a layer of methylammonium lead iodide perovsite that is prepared by sublimation in a high-vacuum chamber and sandwiched between two thin organic charge-transport layers.
Journal ArticleDOI
Molecular Engineering of Push–Pull Porphyrin Dyes for Highly Efficient Dye‐Sensitized Solar Cells: The Role of Benzene Spacers
Aswani Yella,Chi-Lun Mai,Shaik M. Zakeeruddin,Shu-Nung Chang,Chi-Hung Hsieh,Chen-Yu Yeh,Michael Grätzel +6 more
TL;DR: The importance of introducing the phenyl group as a spacer between the BTD and the zinc porphyrin in achieving high power-conversion efficiencies is shown.
