Molecular design of metal-free D–π-A substituted sensitizers for dye-sensitized solar cells

Michael Graetzel, Jacques-Edouard Moser, Shaik Mohammed Zakeeruddin, Robin Humphry-Baker, Joël Teuscher, Davide Di Censo, Mingkui Wang, Nuttapol Pootrakulchote

Novel donor-p-acceptor (D--A) dyes, coded as SD-1, SD-2 and SD-5, were designed and synthesized for dye-sensitized solar cells. All these dyes comprised the same donor and acceptor units while the oligo thiophene units were introduced as linkers between th ...

Inter-Domain Charge Transfer as a Rationale for Superior Photovoltaic Performances of Mixed Halide Lead Perovskites

Jacques-Edouard Moser, Joël Teuscher, Marine Eva Fedora Bouduban, Fabrizio Giordano

Organic-inorganic lead halide perovskites containing a mixture of iodide and bromide anions consistently perform better in donor-acceptor heterojunction solar cells than the standard methylammonium lead triiodide material. This observation is counterintuit ...

Kinetics of the Regeneration by Iodide of Dye Sensitizers Adsorbed on Mesoporous Titania

Michael Graetzel, Jacques-Edouard Moser, Shaik Mohammed Zakeeruddin, Joël Teuscher, Julien Alexandre Andres, Arianna Marchioro, Peng Wang

Regeneration of dye sensitizer molecules by reducing species contained in the electrolyte is a key mechanism in liquid dye-sensitized solar cells because it competes kinetically with a detrimental charge recombination process. Kinetics of the reduction by ...

Dynamics of Photoinduced Interfacial Electron Transfer and Charge Transport in Dye-Sensitized Mesoscopic Semiconductors

Bernard Wenger, Jacques-Edouard Moser, Joël Teuscher, Christophe Bauer

Molecular systems designed for the conversion of solar energy offer ideal models in the study of the kinetics of light-induced electron transfer at surfaces. Due to their high porosity, nanocrystalline oxide semiconductor films allow investigations of inte ...

Charge separation and carrier dynamics in donor-acceptor heterojunction photovoltaic systems

Jacques-Edouard Moser, Majed Chergui, Joël Teuscher, Ursula Röthlisberger, Jan Cornelius Brauer, Alicia Solano, Natalie Renuka Banerji, Ariadni Boziki

Electron transfer and subsequent charge separation across donor-acceptor heterojunctions remain the most important areas of study in the field of third-generation photovoltaics. In this context, it is particularly important to unravel the dynamics of indiv ...

11% efficiency solid-state dye-sensitized solar cells with copper(II/I) hole transport materials

Jacques-Edouard Moser, Shaik Mohammed Zakeeruddin, Joël Teuscher, Ulf Anders Hagfeldt, Norman Pellet, Yiming Cao, Amita Ummadisingu, Fabrizio Giordano, Jingshan Luo, Yasemin Saygili, Marina Freitag

Solid-state dye-sensitized solar cells currently suffer from issues such as inadequate nanopore filling, low conductivity and crystallization of hole-transport materials infiltrated in the mesoscopic TiO2 scaffolds, leading to low performances. Here we rep ...

Control and Study of the Stoichiometry in Evaporated Perovskite Solar Cells

Michael Graetzel, Joël Teuscher, Nicolas Tétreault

Herein, we present the precise stoichiometric control of methlyammonium lead iodide perovskite thin-films using high vacuum dual-source vapor-phase deposition. We found that UV/Vis absorption and emission spectra were inadequate for assessing precisely the ...

Blue-Coloured Highly Efficient Dye-Sensitized Solar Cells by Implementing the Diketopyrrolopyrrole Chromophore

Michael Graetzel, Mohammad Khaja Nazeeruddin, Joël Teuscher, Jun Ho Yum, Thomas Moehl, Thomas Wesley Holcombe, Kasparas Rakstys

The paradigm shift in dye sensitized solar cells (DSCs) - towards donor-pi bridge-acceptor (D-pi-A) dyes - increases the performances of DSCs and challenges established design principles. Framed by this shifting landscape, a series of four diketopyrrolopyr ...

Transforming Hybrid Organic Inorganic Perovskites by Rapid Halide Exchange

Michael Graetzel, Joël Teuscher, Norman Pellet, Joachim Maier

We report on rapid halide exchange in metal halide perovskite of the general formula MAPbX(3) (X = Cl, Br, or I). We find that when the perovskite is infiltrated in a mesoscopic scaffold, halide substitution on the perovskite lattice is strikingly fast, be ...

Unravelling the Potential for Dithienopyrrole Sensitizers in Dye-Sensitized Solar Cells

Michael Graetzel, Jacques-Edouard Moser, Mohammad Khaja Nazeeruddin, Robin Humphry-Baker, Joël Teuscher, Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Negar Ashari Astani, Aswani Yella, Julien Edouard Frey, Peng Gao, Peng Gao, Lauren Elizabeth Polander

Two D−π−A dyes based on the dithieno[3,2-b:2′,3′-d]pyrrole π-bridge (DTP) were synthesized, characterized using UV−vis absorption spectroscopy and electrochemistry, modeled using quantum chemical calculations, and used as sensitizers in dye-sensitized sola ...

Patterning of perovskite-polymer films by wrinkling instabilities

Joël Teuscher

Organic-inorganic perovskites are semiconductors used for applications in optoelectronics and photovoltaics. Micron and submicron perovskite patterns have been explored in semitransparent photovoltaic and lasing applications. In this work, we show that a p ...
