Cost effective natural photo-sensitizer from upcycled jackfruit rags for dye sensitized solar cells
Photo-sensitizers, usually organic dye molecules, are considered to be one of the most expensive com-ponents in dye sensitized solar cells (DSSCs). The present work demonstrates a cost effective and high throughput upcycling process on jackfruit rags to extract a natural photo-active dye and its app...

Photo-sensitizers, usually organic dye molecules, are considered to be one of the most expensive com-ponents in dye sensitized solar cells (DSSCs). The present work demonstrates a cost effective and high throughput upcycling process on jackfruit rags to extract a natural photo-active dye and its application as a photo-sensitizing candidate on titanium dioxide (TiO2) in DSSCs. The jackfruit derived natural dye (JDND) exhibits a dominant photo-absorption in a spectral range of 350 nme800 nm with an optical bandgap of ~1.1 eV estimated from UVevisible absorption spectroscopic studies. The JDND in DSSCs as a major photo-absorbing candidate exhibits a photo-conversion efficiency of ~1.1% with short circuit current density and open circuit voltage of 2.2 mA,cm1/2 and 805 mV, respectively. Further, the results show that the concentration of JDND plays an influential role on the photovoltaic performance of the DSSCs due to the significant change in photo-absorption, exciton generation and electron injection into TiO2. The simple, high throughput method used to obtain JDND and the resulting DSSC performance can be considered as potential merits establishing a cost effective excitonic photovoltaic technology. |
