Journal ArticleDOI
Ligand Engineering for the Efficient Dye-Sensitized Solar Cells with Ruthenium Sensitizers and Cobalt Electrolytes.
Sadig Aghazada,Peng Gao,Aswani Yella,Gabriele Marotta,Thomas Moehl,Joël Teuscher,Jacques-E. Moser,Filippo De Angelis,Michael Grätzel,Mohammad Khaja Nazeeruddin +9 more
TL;DR: Six new cyclometalated ruthenium(II)-based dyes developed through ligand engineering are introduced here and achieved PCEs of up to 9.4% using cobalt(3+/2+)-based electrolytes, which is the record efficiency to date featuring a rUThenium-based dye.
Journal ArticleDOI
Redox Targeting of Insulating Electrode Materials: A New Approach to High-Energy-Density Batteries†
TL;DR: This poster presents a probabilistic procedure to constrain the number of particles in the response of the immune system to the presence of Tau.
Journal ArticleDOI
Symmetric vs. asymmetric squaraines as photosensitisers in mesoscopic injection solar cells: a structure–property relationship study
Jinhyung Park,Claudia Barolo,Frédéric Sauvage,Frédéric Sauvage,Nadia Barbero,Caterina Benzi,Pierluigi Quagliotto,Salvatore Coluccia,Davide Di Censo,Michael Grätzel,Md. K. Nazeeruddin,Guido Viscardi +11 more
TL;DR: A symmetric squaraine and its related non-symmetric structure are shown to have comparable efficiencies in DSCs, but with undoubtedly advantages in the low cost and easiness of synthesis for the symmetrical structure.
Journal ArticleDOI
Long term stability of air processed inkjet infiltrated carbon-based printed perovskite solar cells under intense ultra-violet light soaking
Syed Ghufran Hashmi,Armi Tiihonen,David Martineau,Merve Özkan,Paola Vivo,Kimmo Kaunisto,Ulla Vainio,Shaik M. Zakeeruddin,Michael Grätzel +8 more
TL;DR: In this paper, the long term stability of air processed inkjet infiltrated carbon based perovskite solar cells (CPSCs) is investigated under intense ultra-violet light soaking equivalent to 1.5 Sun UV light illumination.
Journal ArticleDOI
Understanding the Impact of Bromide on the Photovoltaic Performance of CH3NH3PbI3 Solar Cells
M. Ibrahim Dar,Mojtaba Abdi-Jalebi,Neha Arora,Thomas Moehl,Michael Grätzel,Mohammad Khaja Nazeeruddin +5 more
TL;DR: An optimum amount of lead bromide (1%) can enhance the power conversion efficiency of CH3 NH3 PbI3-x Brx devices from 14.7% to 16.9% without altering the bandgap of the perovskite material.
