ItemOrganic Solar Cells Using a High-Molecular-Weight Benzodithiophene-Benzothiadiazole Copolymer with an Efficiency of 9.4%Subbiah, J ; Purushothaman, B ; Chen, M ; Qin, T ; Gao, M ; Vak, D ; Scholes, FH ; Chen, X ; Watkins, SE ; Wilson, GJ ; Holmes, AB ; Wong, WWH ; Jones, DJ (WILEY-V C H VERLAG GMBH, 2015-01-27)A high molecular weight donor-acceptor conjugated polymer is synthesized using the Suzuki polycondensation method. Using this polymer, a single-junction bulk-heterojunction solar cell is fabricated giving a power conversion efficiency of 9.4% using a fullerene-modified ZnO interlayer at the cathode contact.

ItemHexa-peri-hexabenzocoronene in organic electronicsSeyler, H ; Purushothaman, B ; Jones, DJ ; Holmes, AB ; Wong, WWH (WALTER DE GRUYTER GMBH, 2012-01-01)Polycyclic aromatic hydrocarbons (PAHs) are in a class of functional organic compounds with increasing importance in organic electronics. Their tunable photophysical properties and typically strong intermolecular associations make them ideal materials in applications where control of charge mobility is essential. Hexa-peri-hexabenzocoronene (HBC) is a disc-shaped PAH that self-associates into columnar stacks through strong lπ-lΠ interactions. By decorating the periphery of the HBC molecule with various substituents, a range of properties and functions can be obtained including solution processability, liquid crystallinity, and semiconductivity. In this review article, the synthesis, properties, and functions of HBC derivatives are presented with focus on work published in the last five years.
