Abstract
Herein, we report a new type of eco-friendly, cost-effective stainless steel mesh-based flexible quasi-solid dye-sensitized solar cell (DSSC)using electrospun ZnO nanofibers as the photoelectrode. The electrospun ZnO nanofibers showed enhanced surface to volume ratio due to the high porosity of the fibers composed of ZnO grains having 12–20 nm size with high interconnectivity. For DSSCs fabrication, commonly available natural dye chlorophyll was extracted from the Neem plant and used as the dye sensitizer. An overall solar cell conversion efficiency of 0.13 % was observed for the assembled DSSC with a short-circuit photocurrent, open-circuit voltage and fill factor of 28 μA, 0.321 mV and 32.77 %respectively.
