Synthesis and Photophysical Characterization of Cyclometalated Ruthenium Complexes with N-Heterocyclic Carbene Ligands

Mohammad Khaja Nazeeruddin, Sadig Aghazada, Iwan Zimmermann, Valeriu Scutelnic

In the search of new ligand environment for the ruthenium(II) complexes with pyridine-type ligands, we developed seven new cyclometalated ruthenium complexes with N-heterocyclic carbenes (NHCs). In a two-step procedure, we synthesized complexes with the ge ...

High Open-Circuit Voltage: Fabrication of Formamidinium Lead Bromide Perovskite Solar Cells Using Fluorene-Dithiophene Derivatives as Hole-Transporting Materials

Michael Graetzel, Neha Arora, Mohammad Khaja Nazeeruddin, Paul Gratia, Filippo de Angelis, Mohammad Ibrahim Dar, Gwénolé Jean Jacopin, Sadig Aghazada

Four different fluorene dithiophene derivative-based hole-transporting materials (HTMs) (SO7-10) have been synthesized via a facile route and were successfully used in the fabrication of formamidinium lead bromide perovskite solar cells. Detailed character ...

A molecularly engineered hole-transporting material for efficient perovskite solar cells

Michael Graetzel, Michael Saliba, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ulf Anders Hagfeldt, Peng Gao, Filippo de Angelis, Antonio Abate, Juan-Pablo Correa-Baena, Sadig Aghazada

Soln.-processable perovskite solar cells have recently achieved certified power conversion efficiencies of over 20%, challenging the long-standing perception that high efficiencies must come at high costs. One major bottleneck for increasing the efficie ...

Benzotrithiophene-Based Hole-Transporting Materials for 18.2% Perovskite Solar Cells

Michael Graetzel, Paul Gratia, Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Cristina Roldán Carmona, Sadig Aghazada, Inés Garcia Benito

New star-shaped benzotrithiophene (BTT)-based hole-transporting materials (HTM) BTT-1, BTT-2 and BTT-3 have been obtained through a facile synthetic route by crosslinking triarylamine-based donor groups with a benzotrithiophene (BTT) core. The BTT HTMs wer ...

Unraveling the Dual Character of Sulfur Atoms on Sensitizers in Dye-Sensitized Solar Cells

Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Thomas Moehl, Peng Gao, Aswani Yella, Joël Teuscher, Sadig Aghazada

Cyclometalated ruthenium sensitizers have been synthesized that differ with number of thiophene units on the auxiliary ligands. Sensitizers possessing four (SA25, SA246, and SA285) or none (SA282) sulfur atoms in their structures, were tested in solar cell ...
