“…Dye-sensitized solar cells (DSSCs) got attentions of researchers as a promising low-cost solar cell technology since their discovery in 1991 [1][2][3][4][5][6] due to their simple preparation procedure, eco-friendly [7], good performance under diffuse light conditions, reasonably good power conversion efficiency [8,9], colorful natures, and low production cost [11][12]. DSSCs are based on the sensitizing nanocrystalline metal oxide films to visible light through the adsorption of regenerative dyes [13].…”

Dye-sensitized solar cells (DSSCs) are under extensive research works due to their appealing features such as low production costs. The production costs and energy conversion efficiency of DSSCs is strongly influenced by the types of dyes used to harvest photons. Natural dyes extracted from different sources are emerged as a potential candidates to synthetic photosensitizers due to their merit properties including low cost, complete biodegradability, availability and less environmental concern. In order to improve the energy conversion efficiency of natural photosensitizers, blending of different dyes, co-pigmentation of dyes, acidifying of dyes and other approaches have been conducted by researchers, resulting in appreciable performance. This paper reviews the factors affecting the stability of anthocyanin pigments and also the solvents needed for efficient extraction of anthocyanins. Moreover, the potential application of anthocyanin dyes as photosensitizers for DSSC along with the work done over the years is covered.

“…DSSCs, of course, were more interested in photoactive dyes directly extracted from natural sources to reveal what they can do than in what they really are. [5][6][7][8][9][10][11][12] Moreover, the putative advantages of natural dyes, such as reduced cost and increasing flexibility, have driven the replacement of synthetic dyes with naturally derived alternatives in the course of time. [5][6][7][8][9][10][11][12] Furthermore, natural dye-sensitized photoelectrochemical solar cells exhibited respectable photovoltaic conversion efficiencies of up to 2% and with good stability.…”

In an attempt to investigate influence of the utilization of organic dyes on photovoltaic performance of low-cost dye-sensitized solar cells (DSSCs), carminic acid (CA) obtained from cochineal insect was employed as photosensitizer to fabricate DSSCs. To recognize light absorption behavior of the CA, UV-Vis spectroscopy was taken. The CA comprises noticeable spectrum of solar radiation, 430 to 540 nm that makes it appropriate for use as a photosensitizer in DSSCs. Fourier transform infrared (FTIR) spectra of the CA revealed the presence of carboxylic functionality, enabling good anchorage to the surface of TiO 2 . The electrochemical impedance spectroscopy (EIS) analysis manifests that the suppression of the electron recombination at the TiO 2 /CA/electrolyte interface was insufficient. Quantum chemical calculations of the CA dye were performed by using the density functional theory (DFT). The lowest unoccupied molecular orbital (LUMO) level of the CA matched well for the injection of electron from the CA to the conduction band edge of TiO 2 . The achieved photo-conversion efficiency of a DSSC employing the CA photosensitizer was 1%, which was found to be much higher than that of several natural dyesbased DSSCs under a simulated solar light illumination of 100 mW/cm 2 .

Dye‐sensitized solar cells (DSSCs) have turned a new horizon in energy research due to their widespread exploration over two decades by improving efficiency, cost‐effectiveness, and easy process than inorganic‐based solar cells. The major challenges are metal complexes on designing the cells and sustainability implications for further rapid expansion due to its toxicity. To overcome the problems associated with metal complexes, the dyes are extracted from bionatural sources such as flowers, fruits, barks, petals, roots, leaves, and beans of plants. These organic dyes are being nontoxic, cost‐effective, abundant, environmentally friendly, and easy to extract, which is made them extensively applicable for DSSC. Through this review, readers may get an idea about the effect in the efficiency of the solar cell by applying variable semiconductors, effects of solvents, variable light‐harvesting pigments, types of electrolytes, and modification of counter electrodes by certain polymeric materials or nanomaterials. Furthermore, the effects of methodology, processing temperature, and pH of the medium during synthesis on solar cell parameters, such as the efficiency of DSSC, are critically analyzed which are reported by other researchers.
