Thickness dependence, in situ measurements, and morphology of thermally controlled interdiffusion in polymer-C-60 photovoltaic devices
(American Physical Society, 2004-04-28)
A series of detailed studies is presented in which heat-induced interdiffusion is used to create a gradient bulk-heterojunction of 2-methoxy-5-(2(')-ethylhexyloxy)-1,4-phenylenevinylene (MEH-PPV) copolymer and C-60. Starting ...
