The DSSC fabricated using the novel mixed dye (ABC) mixture gave the highest efficiency of 3.73%, however it showed similar drop (almost 22%) in efficiency as that with of N3 dye in stability studies. Still, there is lot of scope for the replacement of current DSSC materials due to their high cost, less abundance, and long-term stability. A quantitative analysis of the temperature-dependent photoluminescence spectra of the CdS NWs was carried out. 7. If the ratio exceeds a certain threshold.
