Applications

PCPDTBT, copolymer of cyclopenta dithiophene and benzothiadiazole, is a low band-gap polymer semiconductor that is widely used for high-performance OPV devices with excellent charge-carrier properties.

Like PSBTBT, PCPDTBT has an ideal bandgap value (1.5 eV). This not only covers a broad range in the visible light spectrum, but also extends its spectral absorption into the infrared region.

In most cases, PCPDTBT is considered to be amorphous due to its non-linear side-chain structures. However, highly-crystalline films of PCPDTBT with branched side-chains can also be achieved by solvent vapour crystallisation [2].
