    Fabrication of metal organic framework/Polyoxometalate-TiO2 based DSCCs with enhanced electron lifetime and reduced recombination of charge carriers sensitized with cabbage/spinach cocktail natural dyes by William Moloto, Pontsho Mbule, Edward Nxumalo, Bulelwa Ntsendwana

    Published 2025-04-01
    “…The TiO2-FeBTC-BiPOM (6 %) nanocomposites doped with 400 ​μg/mL CQDs exhibited improved performance with lower charge transfer resistance. As a result, this electrode was used to fabricate a novel natural dye (chlorophyll, anthocyanin and cocktail mixture)-based DSSCs.The cocktail based mixture showed higher power conversion efficiency of 1.92 % compared to spinach based DSSCs (0.98 %) and purple cabbage (0.89 %) under 100 ​mW/cm2 light illumination with 30 ​ms of electron lifetime, which is three times and four times more than spinach and cabbage based DSSCs respectively. …”
