A linear non-halogenated polymer donor via Suzuki–Miyaura coupling for organic solar cells†
Abstract
A novel linear non-halogenated polymer donor, PTTzP, with a simple structure was synthesized via Suzuki–Miyaura coupling. PTTzP exhibits comparable device performance (>12%) in organic solar cells (OSCs) when processed with halogenated and non-halogenated solvents, respectively. This achievement highlights the potential of PTTzP as an efficient and environmentally friendly polymer donor, enabling high-performance OSCs through entirely green synthesis and processing methods.
