Alkylpyrrolidiniumtrialkoxysilyl iodides as organic iodide sources for dye-sensitised solar cells
Naomi Lewcenko,Matthew John Byrnes,Yi-Bing Cheng,Shaik M. Zakeeruddin,Michael Grätzel,Leone Spiccia +5 more
TL;DR: Two new alkylpyrrolidiniumtriethoxysilyl iodides have been developed as iodide sources for DSSCs; the compound with an undecyl spacer between the siloxane and the pyrrolids moieties furnished higher open circuit voltages than the propyl analogue and higher efficiencies at low light intensity.
Book ChapterDOI
Properties and applications of nanocrystalline electronic junctions
TL;DR: A paste containing the nanocrystalline semiconductor particles is applied by screen printing or doctor blading on a glass coated with a transparent conducting oxide (TCO) layer made of fluorine-doped SnO2.
Journal ArticleDOI
RETRACTED: Advances in colloidal quantum dot solar cells: The depleted-heterojunction device
Illan J. Kramer,Andras G. Pattantyus-Abraham,Aaron R. Barkhouse,Xihua Wang,Gerasimos Konstantatos,Ratan Debnath,Larissa Levina,Ines Raabe,Md. K. Nazeeruddin,Michael Grätzel,Edward H. Sargent +10 more
TL;DR: In this article, a depletion region was established for field-driven charge transport and separation, and the resulting depleted-heterojunction solar cells provided a 5.1% AM1.5 power conversion efficiency.
Journal ArticleDOI
