Indole is an organic compound with the formula C6H4CCNH3. Indoles are derivatives of indole where one or more H's have been replaced by other groups. Indole is classified as an aromatic heterocycle. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered pyrrole ring. It is shown that replacing branched side chains by linear ones in the BDT motifs induces a critical change in polymer self-assembly and backbone orientation in thin films that correlates with a dramatic drop in solar cell efficiency, making PBDTTPD one of the best polymer donors for use in the high-band-gap cell of tandem solar cells.
