We report a series of "donor-free" dyes featuring moieties of oligo(4,4-dihexyl-4H-cyclopenta[1,2-b:5,4-b']dithiophene) (CPDT) functionalized with cyanoacrylic end groups for mesoscopic titania solar cells based on I-/I-3(-) or Co(II)/Co(III) redox couple ...
The present invention concerns novel silolothiophene-bridged triphenylamines and related compds. and their use as hole transport materials (HTM), for example in optoelectronic and/or electrochem. devices. These materials are particularly useful in org.-ino ...
