ABSTRACT

We report a simple photoelectrochemical cell (PEC) using a derivative of borondipyrromethane  (BODIPY), that is, (4,4-difluoro-1,3,5,7,8-pentamethyl-2,6-diethyl-4-bora-3a,4a-diaza-s-indecene) as dye sensitizer and an aqueous electrolyte containing Ferric/ferrous redox couple (F+++/Fe++). Under white light illumination of intensity ~ 1mW/cm2, the open circuit voltage and short-circuit current of the PEC was found to be respectively, 180 mV and 1.3 μA/cm2.
