of ferrocenyl moieties with a cyanovinyl system
using a unique solid-state synthetic method led to the formation of
donor–acceptor type compounds with wide absorption in the visible
region. A DSSC study using the ferrocenyl cyanovinyl compound as a
dye with an electrolyte-free fabrication system showed an unprecedented
open-circuit voltage (VOC) of 763–841
mV. DFT calculations were carried out to understand an unique electron
transfer mechanism for the DSSC device which may be responsible for
the high VOC.
