High performance donor materials representative

HGURE 5.2 (A) Structures of conducting polymers. (B) Representative high performance donor materials in polymer solar cell. (C) Representative fused aromatic ring building blocks for high performarxe donor materials. 

The innovations in materials science boost the development of polymer solar cell. Considering the four aspects mentioned previously, three methods have been developed accordingly (Li, 2012), namely side chain engineering, donor-acceptor (D-A) copolymerization and large fused aromatic ring structure. Some of the representative high performance conjugated polymers are displayed in Fig. 5.2B.
