We prepared the ternary blends active layer by incorporating a new two-dimensional donor-
acceptor (D/A) conjugated polymer (BDTTBO) comprising benzo-dithiophene-thiophene …

Several approaches, including the use of small molecule acceptors, novel polymer
structures, and tandem cell structures, have been adopted to prepare polymer solar cells …

Two new D–A donor polymers of PBDTNS-DTBO and PBDTNS-DTBT are designed and
synthesized with a two-dimensional alkylthionaphthyl-substituted benzo [1, 2-b: 4, 5-b′] …

Low bandgap and two-dimensional (2D)-conjugated copolymers based on benzo [1, 2-b: 4,

Rational molecular design of conjugated polymers and cautious optimization of
morphologies of the active layer are critical for developing high performance polymer solar …

Ternary bulk heterojunctions (BHJs) are promising candidates that can improve the power
conversion efficiencies (PCEs) of organic solar cells (OSCs). In this paper, a ternary OSC …
