The paper explored the mechanism of working of dye sensitizers for the improvement of efficiency of environmentally benign dye-sensitized solar cells (DSSC). The identified natural dyes namely anthocyanin (A), betalain (B) and chlorophyll (C) were extracted from Roselle (Hibiscus sabdariffa L.), spinach (Spinacia oleracea) and beetroot (Beta vulgaris) respectively. Light absorption performance of dyes was recorded by ultraviolet-visible (UV-vis) spectroscopic analysis followed by direct and indirect band gap calculation. The effect of functional groups present in the dyes studied by Fourier transform infrared spectroscopy (FTIR) and binding of the dyes on TiO 2 through surface morphology of sheets was identified employing field emission scanning electron microscopy (FESEM). Photovoltage characteristics (I-V) and induced photon to current efficiency (IPCE) measurements were also noted followed by the stability studies. The N3 (synthetic dye chosen for the reference) dye-based cell showed the highest efficiency of 6.19% out of all of 11 cells fabricated using different sensitizers. The DSSC fabricated using the novel mixed dye (ABC) mixture gave the highest efficiency of 3.73%, however it showed similar drop (almost 22%) in efficiency as that with of N3 dye in stability studies. The mechanism for the increase in the overall power conversion efficiency of DSSC was also suggested.

“…The typical OWSC may have the following con guration: a semiconductor/sensitizer/redox agent/cathode interface, where each layer could be formed from or complemented by an organic waste-derived material. These layers are often sandwiched between glass substrates, usually transparent conductive oxides (TCOs), such as uorine-doped tin oxide (FTO), indium-doped tin oxide (ITO) or aluminum-doped zinc oxide (AZO) (Patni et al, 2018). About 12% of all TiO 2 produced is utilized by the paper industry because it has a high refractive index, which yields high opacity to the paper produced (Council, 2012).…”

Organic waste-derived solar cells (OWSC) are a classi cation of third-generation photovoltaic cells in which one or more of its constituents are fabricated from organic waste material. They are an inspirational complement to the conventional thirdgeneration solar cell with the potential of revolutionizing our future approach to solar cell manufacture. This article provides a study and summary of solar cells that fall under the category of OWSC. OWSC own their merit to low cost of manufacturing and environmental friendliness. This review article reveals different organic waste raw materials, preparation-to-assembly methodologies and novel approaches to solar cell manufacturing. Ideas for the optimization of the performance of OWSC are presented. The assembly con gurations and photovoltaic parameters of reported OWSC are compared in detail. An overview of the trends pertaining to the research regarding OWSC in the past decade is given. Also, advantage and disadvantage of the different solar cell technologies are discussed and possible trends are proposed. Industrial organic waste raw materials such as paper, coal and plastics are amongst the least explored and yet most attractive for solar cell fabrication. The power conversion e ciencies for the cited works are mentioned while emphasizing the products and functions of the organic waste raw materials used.

eter [4]. Thin-film solar cell based on a multinary compound Cu(In, Ga)Se2 has an efficiency of 20% [5].A dye-sensitized solar cell belongs to third-generation solar cells, which have higher efficiency than a thin film-based solar cell. It was introduced by Gratzel and O'Regan in 1991. Michael Gratzel was awarded the 2010 Millennium Technology Prize for his contribution in the field of solar cells [6]. The basic structure of the dye-sensitized solar cell is made up of semiconductor coated photoanode electrode, sensitizer, electrolyte, and counter electrode [7].Dye-sensitized solar cells are a subgroup of photoelectrochemical solar cells since they both depend on an electrolyte. They have a couple of additional features like an organic or organometallic dye sensitizer and a nanoparticulate semiconductor rather than a solid crystal semiconductor. They are a potentially significant development in solar technology, with efficiencies up to 11% reported in the literature [8]. But later, 15% solar cell efficiency as a prototype was introduced [9]. When the zinc-oxide nanorods are deposited, the quantum efficiency is enhanced [10].While dye-sensitized solar cells do not have as high efficiency as their conventional silicon counterparts, there are already advantages for this new technology. The first and most obvious advantage is their low cost. Due to cheaper starting materials, ease of production, dye-sensitized solar cells are comparatively much less expensive to prepare in comparison with silicon crystal solar cells. Also, their overall production is less detrimental to the environment than the output of conventional silicon cells [11]. Furthermore, dye-sensitized solar cells have considerable flexibility in shape, colour, transparency, and performance also under diffuse light [12,13]. Dye-sensitized solar cells could be incorporated into massive varieties of products, e.g. hand baggage, building assimilated photovoltaics for walls of buildings or windows [14][15][16].
