Journal ArticleDOI
Porphyrin-Sensitized Solar Cells with Cobalt (II/III)–Based Redox Electrolyte Exceed 12 Percent Efficiency
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 ArticleDOI
Highly Efficient Mesoscopic Dye-Sensitized Solar Cells Based on Donor-Acceptor-Substituted Porphyrins
TL;DR: A greatly enhanced photovoltaic performance is observed when the porphyrin dye is cosensitized with a metal-free dye that has a complementary spectral response.
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.
Journal ArticleDOI
Novel zinc porphyrin sensitizers for dye-sensitized solar cells: synthesis and spectral, electrochemical, and photovoltaic properties.
Cheng-Wei Lee,Hsueh-Pei Lu,Chi-Ming Lan,Yi-Lin Huang,You-Ren Liang,Wei-Nan Yen,Yen-Chun Liu,You-Shiang Lin,Eric Wei-Guang Diau,Chen-Yu Yeh +9 more
TL;DR: Quantum-chemical (DFT) results support the spectroelectrochemical data for a delocalization of charge between the porphyrin ring and the amino group in the first oxidative state of diarylamino-substituted p Morphyrin 5, which exhibits the best photovoltaic performance among all theporphyrins under investigation.
Journal ArticleDOI
Synthesis and characterization of porphyrin sensitizers with various electron-donating substituents for highly efficient dye-sensitized solar cells
Chou-Pou Hsieh,Hsueh-Pei Lu,Chien-Lan Chiu,Cheng-Wei Lee,Shu-Han Chuang,Chi-Lun Mai,Wei-Nan Yen,Shun-Ju Hsu,Eric Wei-Guang Diau,Chen-Yu Yeh +9 more
TL;DR: In this paper, a series of porphyrin dyes with an electron-donating group (EDG) attached at a meso-position (YD1-YD8) have been designed and synthesized for use as sensitizers in dye-sensitized solar cells (DSSC).
