Journal ArticleDOI
All-Polymer Solar Cells Based on a Conjugated Polymer Containing Siloxane-Functionalized Side Chains with Efficiency over 10.
TL;DR: A novel wide-bandgap conjugated copolymer based on an imide-functionalized benzotriazole building block containing a siloxane-terminated side-chain is developed and can be a promising candidate toward high-performance all-PSCs for practical applications.
Journal ArticleDOI
Silole‐Containing Polymers: Chemistry and Optoelectronic Properties
Junwu Chen,Yong Cao +1 more
TL;DR: In this article, the synthesis and optoelectronic properties of various π-conjugated-, σ-conjunctional, σconjugation-, ρ-conjunctive-, pendanted-, and hyperbranched or dendritic silole-containing polymers (SCPs) are described.
Journal ArticleDOI
Largely enhanced efficiency with a PFN/Al bilayer cathode in high efficiency bulk heterojunction photovoltaic cells with a low bandgap polycarbazole donor.
TL;DR: Judicious design of a polymer donor and selection of a fullerene acceptor have realized high effi ciency BHJ PVCs with PCE values over 5% and tremendous efforts have also been made to optimize the active layer formation and the device confi guration.
