“…Natural dyes are advised as the best feasible sensitizer to overcome the disadvantages of synthetic sensitizers. Natural sensitizers are cheaper, affordable, abundant, and eco-friendly (18,19). They have multi-pigment options and high absorption coefficient enabling electrons excitation from HOMO to LUMO and electrons injection into the semiconductor efficiently (21).…”

Methanol extracts of onion peel waste (Allium cepa) were applied as natural sensitizer in Dye-Sensitized Solar Cell (DSSC) fabrication. This research investigated the dye characteristics of onion peel extract and its power conversion efficiency. Onion peel extraction was carried out using unacidified methanol extract (UME) and acidified methanol extract (AME). Dye absorption was characterized by UV-Vis Spectrophotometer at a wavelength of 200-800 nm and FT-IR at a wave number of 4000-500 cm-1. The power conversion efficiency of the fabricated DSSC was determined by calculating the voltage and current generated by the multimeter. The red onion peel extracts, both acidified and unacidified methanol, had maximum absorption at UV-Visible range (457, 659 and 662 nm). Onion peel extract has several functional groups such as –OH, C=O, C-O-C, C=C, and C-H aromatics- showing specific absorption corresponding to the anthocyanin structure. A solar energy conversion efficiency of η= 0.0413% was obtained from UME extract with a short circuit current of up to Jsc=0.6031 mAcm-2 and a fill factor of 0.2764.

“…Consequently, a slight increase in power values (from 0.08024 µW to 0.09284 µW) was observed when transitioning from 5 mins to 12 h of soaking time. This increase was attributed to the improved coverage of the dye layer, facilitating enhanced charge transfer from the conduction band of the TiO 2 surface to the electrolyte [37]. The mechanism behind this improvement in charge transfer was the higher number of electrons transferred within the photoelectrodes.…”

Solar cells are pivotal in harnessing renewable energy for a greener and more sustainable energy landscape. Nonetheless, eco-friendly materials for solar cells have not been as extensive as conventional counterparts, highlighting a significant area for further investigation in advancing sustainable energy technologies. This study investigated natural dyes from cost-effective and environmentally friendly blueberries and mulberries. These dyes were utilized as alternative sensitizers for dye-sensitized solar cells (DSSCs). Alongside the natural dyes, a green approach was adopted for the DSSC design, encompassing TiO2 photoanodes, eco-friendly electrolytes, and green counter-electrodes created from graphite pencils and candle soot. Consequently, the best-optimized dye sensitizer was mulberry, with an output power of 13.79 µW and 0.122 µW for outdoor and indoor environments, respectively. This study underscored the feasibility of integrating DSSCs with sensitizers derived from readily available food ingredients, potentially expanding their applications in educational kits and technology development initiatives.

“…Anthocyanin is one of the natural pigments easily found in onion biowaste. It is a watery soluble compound and contains carbonyl (C=O) and hydroxyl group (OH) that can be absorbed to the TiO2 surface and stabilize the excited states (12)(13)(14). Anthocyanin shows a wide absorption band in the visible light spectrum and accelerates the electronic transitions of the dye molecules.…”

In the present paper, two natural photosensitizers extracted from red onion peels have been experimentally studied to sensitize the photovoltaic cells. The two natural dyes were prepared overnight, soaking the red onion peel powder in distilled water without acidification (UW) and acidified water (AW). Dye characteristics were identified by UV-vis Spectrophotometer and FT-IR Spectrophotometer. The cell performance was assessed by calculating the produced voltage and current by multi-meter. Red onion peel dyes absorb visible light at a wavelength of 507 nm and promote electron transfer into the porous semiconductor surface. A higher power conversion efficiency (η=0.0535 %) was featured by an unacidified solvent with a short circuit current density (Jsc) of 0.96 mA.cm-2, an open circuit voltage (Voc) of 338 mV and a fill factor of 0.2576. This paper presents a fascinating preliminary study to develop renewable and sustainable energy sources using bulky biowaste.
