Excitation dynamics of a low bandgap silicon-bridged dithiophene copolymer and its composites with fullerenes
(2012)We report on excitation dynamics in pristine and bulk heterojunction films of the low bandgap silicon-bridged dithiophene copolymer poly[(4,4′-bis(2- ethylhexyl)dithieno[3,2-b:2′, 3′-d]silole)-2,6-diyl-alt-(4,7-bis(2- ...

Monitoring charge exchange in P3HT-nanotube composites using optical and electrical characterisation
(2009)Charge exchange at the bulk heterojunctions of composites made by mixing single wall nanotubes (SWNTs) and polymers show potential for use in optoelectronic devices such as solar cells and optical sensors. The density/total ...

Size-dependent charge transfer in blends of Pbs quantum dots with a low-gap silicon-bridged copolymer
(2013)The photophysics of bulk heterojunctions of a high-performance, low-gap silicon-bridged dithiophene polymer with oleic acid capped PbS quantum dots (QDs) are studied to assess the material potential for light harvesting ...
