Summary: In this study, the flower extracts of red and yellow Canna lily were used as photosensitizers for natural dye-sensitized solar cells. A compact layer was added below the ZnO semiconductor to reduce recombination rate and improve photovoltaic performance. The addition of the compact layer resulted in increased current density, voltage, and charge collection efficiency for both dyes. This enhancement can be attributed to improved electron lifetime, diffusion length, and reduced series resistance. Despite the presence of defects in the ZnO photoanode, the Canna dyes produced significantly enhanced photovoltage. The impact of the compact layer on the photovoltaic parameters was confirmed through EIS study.
