Why bis (۱,۲,۴,۵-ben zentetracarboxylic) nitrato ruthenium (II) is not suitable case for dye sensitized soalr cell application?

The c onversion of sunlight to electricity using dye-se nsitized solar cells (DSC s) represen ts one of the most promising method s for future large scale power produ ction from renewable energy source s.Briefly DSCs contain five components: (۱) a conductiv e mechanic al support, (۲) a wideband gap se miconductor film,(۳) a sensitizer,(۴) electrolyte or hole conductor,and (۵) a count er electrode.The sensitizer is a key component harvesting the solar radiation and converting it to electric curren t by electron injection into the wid e band gap s emiconductor.As the m ost successf ul sensitizers to date, ruthenium com plexes used in conjunction with an ionic liquid electrolyte to overco me leakage problems of volatile electrolyte s have exhibited remarkable efficiency and sta bility.[۱]
