Graphene nanoplatelets outperforming platinum as the electrocatalyst in co-bipyridine-mediated dye-sensitized solar cells.
TL;DR: Graphene nanoplatelets in the form of thin semitransparent films on F-doped SnO2 (FTO) exhibit high electrocatalytic activity for the Co(bpy)3(3+/2+) redox couple in acetonitrile electrolyte solution.
Journal ArticleDOI
Mesoscopic solar cells for electricity and hydrogen production from sunlight
TL;DR: The quality of human life depends to a large degree on the availability of energy sources as mentioned in this paper and the present annual worldwide energy consumption has already attained a level of over 400 exajoules and is...
Journal ArticleDOI

TL;DR: A combined experimental and theoretical study on the origin of the different open circuit potentials observed in dye-sensitized solar cells using Ru(II)-polypyridyl homoleptic and heteroleptic sensitizers is reported.
Journal ArticleDOI
Cyclopentadithiophene Bridged Donor–Acceptor Dyes Achieve High Power Conversion Efficiencies in Dye‐Sensitized Solar Cells Based on the tris‐Cobalt Bipyridine Redox Couple
Hoi Nok Tsao,Chenyi Yi,Thomas Moehl,Jun-Ho Yum,Shaik M. Zakeeruddin,Mohammed Khaja Nazeeruddin,Michael Grätzel +6 more
TL;DR: This work presents a new mesoporous composite material that can be used for dye-sensitized solar cells and its applications in photovoltaics and transport and performance research.
Journal ArticleDOI
Diffusion engineering of ions and charge carriers for stable efficient perovskite solar cells
Enbing Bi,Han Chen,Fengxian Xie,Yongzhen Wu,Wei Chen,Yanjie Su,Ashraful Islam,Michael Grätzel,Xudong Yang,Liyuan Han,Liyuan Han +10 more
TL;DR: A nanostructured carbon layer is designed to suppress the diffusion of ions/molecules within perovskite solar cells, an important degradation process in the device, and this nanocarbon layer benefited the diffusionof electron charge carriers to enable a high-energy conversion efficiency.
