Conjugated Mesopolymer Achieving 15% Efficiency Single-Junction Organic Solar Cells.

ABSTRACT: The high-performance organic solar cells (OSCs) tend to choose the polymers with high molecular weight as donors, which easily produce good crystallinity to facilitate intermolecular charge transfer. However, these polymers usually accompanied by the low solubility and synthetic difficulty, increasing batch-to-batch variations. The proposal of conjugated mesopolymers (molar mass (M_n ) in 1-10 kDa) can overcome these problems. Herein, a new mesopolymer, MePBDFCl_H as donor material is designed and synthesized, and firstly applied in OSCs. As a comparison, other lower molecular weight mesopolymer of MePBDFCl_L and higher molecular weight polymer of PBDFCl with same structure are also prepared and investigated. Because of its appropriate phase separation and mis
