Journal ArticleDOI
Influence of the counter electrode on the photovoltaic performance of dye-sensitized solar cells using a disulfide/thiolate redox electrolyte
Julian Burschka,Vincent Brault,Shahzada Ahmad,Shahzada Ahmad,Livain Breau,Mohammad Khaja Nazeeruddin,Benoît Marsan,Shaik M. Zakeeruddin,Michael Grätzel +8 more
TL;DR: In this paper, the influence of different counter electrode materials on the photovoltaic performance of dye-sensitized solar cells employing disulfide/thiolate-based redox electrolyte has been systematically studied.
Journal ArticleDOI
Electrochromic devices based on surface-modified nanocrystalline TiO2 thin-film electrodes
TL;DR: In this article, a cone-shaped trimeric arborol-type viologen was prepared with the intention to fill out the space above the convex surface of the nanoparticles particularly well.
Journal ArticleDOI
Molecular photovoltaics that mimic photosynthesis
TL;DR: In this article, a photo-voltaic cell based on molecular light absorbers and mesoporous electrodes was developed, and the certified overall power conversion efficiency of the new solar cell for standard air mass 1.5 solar radiation stands presently between 10 and 11.
Journal ArticleDOI
Self-Assembled Monolayers as Interfaces for Organic Opto-electronic Devices
Libero Zuppiroli,L. Si-Ahmed,Katalin Kamarás,Frank Nüesch,M. N. Bussac,Dominique Adès,Alain Siove,Ellen Moons,Michael Grätzel +8 more
TL;DR: In this paper, a self-assembled monolayer of functionalized molecules grafted on an organic semiconductor electrode is used to reduce the Schottky barrier between the conductive electrode and the organic semiconductors.
Journal ArticleDOI
High Molar Extinction Coefficient Organic Sensitizers for Efficient Dye-Sensitized Solar Cells
Hyunbong Choi,Ines Raabe,Duckhyun Kim,Francesca Teocoli,Chulwoo Kim,Kihyung Song,Jun-Ho Yum,Jaejung Ko,Md. K. Nazeeruddin,Michael Grätzel +9 more
TL;DR: Solar-cell devices based on the sensitizer JK-113 in conjunction with a volatile electrolyte and a solvent-free ionic liquid electrolyte gave high conversion efficiencies of 9.1% and 7.9%, respectively.
