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

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

Ternary strategy is a promising approach to broaden the photoresponse of polymer solar
cells (PSCs) by adopting combinatory photoactive blends. However, it could lead to a more …

Triggered by the energy crisis and the demand on the clean energy sources in the future,
organic solar cells especially conjugated polymer based polymer solar cells (PSCs) arise …

In this study we synthesized the donor–acceptor conjugated copolymers PBTT4BT and
PBTT4BO featuring benzotrithiophene (BTT) units as donors and benzothiadiazole (BT) and …

Bulk heterojunction (BHJ) polymer solar cells (PSCs) sandwich a blend layer of conjugated
polymer donor and fullerene derivative acceptor between a transparent ITO positive …

Organic photovoltaics (OPV), especially bulk-heterojunction (BHJ) polymer solar cell, has
become a promising candidate in the development of low-cost, lightweight, and flexible …

Extending π-conjugation in the benzodithiophene (BDT) side chains has been proven useful
to improve the efficiencies of the BDT-based polymer solar cells (PSCs). Herein, combined …

Fusing bithiophene units with a benzo moiety, benzo [2, 1-b: 3, 4-b′] dithiophene (BDT),
was projected by theoretical calculations to lower the highest occupied molecular orbital …

By adopting a series of donor–acceptor (D–A) polymers containing Benzo [1, 2-b: 4, 5-b′]
dithiophene (BDT) and thieno [3, 4-c] pyrrole-4, 6-dione (TPD) with different numbers of alkyl …
