Functionalization 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 (V_OC) 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 V_OC.

基于双功能二茂铁基氰乙烯基分子作为染料和氧化还原对的无电解质染料敏化太阳能电池，具有高开路电压

二茂铁基部分通过氰基乙烯基系统使用独特的固态合成方法进行功能化，导致形成了在可见光区域具有广泛吸收的供体-受体型化合物。DSSC研究使用二茂铁基氰基乙烯基化合物作为染料，采用无电解质的制造系统，显示出前所未有的763-841 mV开路电压（V _OC）。进行DFT计算是为了了解DSSC器件独特的电子转移机理，该机制可能是高V _OC的原因。
