Abstract

Abstract : Panchromatic engineering of room temperature chemically assembled ZnO anodes with low acidity porphyrin and indoline dyes for use in flexible solar cells. Abstract : In this work, panchromatic engineering of room temperature (RT) chemically assembled ZnO anodes has been investigated using low acidity porphyrin and indoline dyes, i.e. YD2-o-C8-TBA and D149, for application in flexible dye-sensitized solar cells (DSSCs). The photovoltaic performance of the YD2-o-C8-TBA/D149 co-sensitized ZnO DSSC was optimized using ZnO anodes prepared on indium tin oxide (ITO)-coated glass substrates. The short-circuit current density of the optimized co-sensitized ZnO DSSC is 10% and 75% higher than those of the individual D149-sensitized and YD2-o-C8-TBA-sensitized cells, respectively. Compared to the D149-sensitized cell, the YD2-o-C8-TBA/D149 co-sensitized ZnO DSSC with a wavelength ranging from 475–700 nm exhibited improved photon-to-current conversion efficiencies. The optimized cell efficiency of 5.6% is accounted for by the rigid co-sensitized ZnO DSSC. Due to the RT fabrication of the ZnO anode, a comparable photovoltaic performance is attained with the co-sensitized ZnO DSSC fabricated using the ITO-coated plastic substrates. An efficiency of 5.3% is monitored in the flexible co-sensitized ZnO DSSC.
