Investigation of the use of food waste in renewable energy production: Extraction, fabrication and characterization of natural photosensitizers in DSSCs
In this research, two important categories of environmental protection and green energy production have been studied. In this way, agricultural waste has been used to prepare photosensitizers in order to reduce the waste produced in the agricultural and food industry in addition to introducing sustainable materials for dye-sensitized solar cells (DSSCs). For this end, Eggplant peel, Sour cherry waste and Red grape waste, which are unavoidable sources of food industry, have been used to prepare natural sensitizer. Extraction was done in water and ethanol and used for FTIR, UV–Vis and CV analysis. The extracts had a bathochromic shift in ethanol compared to water. The CV test results showed that the extracts prepared in water and ethanol are suitable for use in the DSSCs. DSSCs was prepared using titanium dioxide as a semiconductor, extracts in water and ethanol, and platinum and GO/MoS2 nanocomposite in counter electrode. AM 1.5 light was chosen to study the photovoltaic performance and the prepared devices were evaluated. In this research, the effect of solvent and counter electrode on the DSSCs efficiency was investigated. The highest efficiency for the extract obtained from eggplant peel in ethanol and in the presence of platinum is about 1.49 %.
期刊介绍：
Encouraging a transition to a sustainable energy future is imperative for our world. Technologies that enable this shift in various sectors like transportation, heating, and power systems are of utmost importance. Sustainable Energy Technologies and Assessments welcomes papers focusing on a range of aspects and levels of technological advancements in energy generation and utilization. The aim is to reduce the negative environmental impact associated with energy production and consumption, spanning from laboratory experiments to real-world applications in the commercial sector.
