Recent Progress, Advancements, and Efficiency Improvement Techniques of Natural Plant Pigment‐Based Photosensitizers for Dye‐Sensitized Solar Cells

“…Before dye-sensitized solar cells (DSSCs), silicon-based solar cells were found to be the most popular and dominant source of energy [18]. These solid-state junction devices dominated the photovoltaic industry.…”

Co-sensitization effect of N719 dye with Cu doped CdS colloidal nanoparticles for dye sensitized solar cells

“…In that scenario, natural and metal-free organic dyes have become an alternative sensitisation method to reduce synthetic dyes' significant drawbacks. However, the adsorption ability and performance evaluation were weaker than the synthetic metal-organic dyes [5]. They also exhibit weaker light stability than metal-based sensitizers; hence, the co-sensitization strategy is applied to broaden the light absorption spectra.…”

Performance Evaluation of Natural Dye-Sensitized Solar Cells: A Comparison of Density Functional Theory and Experimental Data on Chlorophyll, Anthocyanin, and Cocktail Dyes as Sensitizers

“…Over the past years, natural dyes have worked as photocatalysts and photosensitizers in DSSCs. − Natural dyes are organic molecules that can be extracted from plants, fruits, vegetables, flowers, or insects and should absorb all light. − The conversion efficiency of DSSCs can be improved by adjusting the pH value of the dye . Lowering the pH value of the dye can lead to an increase in the efficiency by a factor of 2 .…”
