Journal ArticleDOI
Efficient Green-Light-Emitting Diodes from Silole-Containing Copolymers
TL;DR: Two random copolymers based on poly(n-hexylfluorene-co-4,4-diphenyldithienosilole) (PF-DTS) were synthesized by Suzuki coupling reaction as mentioned in this paper.
Journal ArticleDOI

TL;DR: In this article, a new generation of NLO dendrimers has been developed to generate well-defined nano-objects, minimize strong intermolecular electrostatic interactions, and improve poling efficiency and stability.
Journal ArticleDOI
Tailoring the Functionality of Organic Spacer Cations for Efficient and Stable Quasi‐2D Perovskite Solar Cells
Journal ArticleDOI
Ideal Bandgap Organic-Inorganic Hybrid Perovskite Solar Cells.
TL;DR: A new ideal bandgap absorber composition is rationally designed and developed, which possesses lower nonradiative recombination states, band edge disorder, and Urbach energy coupled with a higher absorption coefficient, which yields a reduced Voc,loss and improved PCE for the derived PVSCs.
