Abstract
Natural pigments containing anthocyanidins extracted from 14 fruit samples were studied as possible sensitizers for the fabrication of dye-sensitized solar cell (DSSC). The Dyes extracted from pomegranate and berry families are reported as candidates for DSSC with a lead current between 0.5-3.98 (mA) and a voltage of 150-350 (mV), and so could be used as photosensitizers in the construction of affordable and low cost DSSC especially for educational purposes. Based on direct sunlight illumination, pomegranate dye had the maximum efficiency in energy conversion (0.22%) followed by, raspberry (0.16%), blackberry (0.14%), blueberry (0.05%) and red grape (0.02%).
Highlights
The highest reported performance for Dye-Sensitized Solar Cell (DSSC) efficiency is about 13% [3]
Dyes employed in making DSSC usually consist of a transition metal complex of ruthenium or osmium [4]
The use of a natural product such as dye extracted from fruits insures the fabrication of inexpensive and eco-friendly solar cells
Summary
The high cost and environmental concerns in use of fossil fuels have piloted innovative techniques that aim to efficiently convert solar energy into electrical energy. Dye-Sensitized Solar Cell (DSSC) shows an economical and environmentally friendly credible alternate model to other forms photovoltaic devices [1]. Michael Grätzel first reported dye-sensitized solar cells in 1991 and has since been a topic of great interest to many researcher in the scientific community [2]. The highest reported performance for DSSC efficiency is about 13% [3]. Dyes employed in making DSSC usually consist of a transition metal complex of ruthenium or osmium [4]. The use of a natural product such as dye extracted from fruits insures the fabrication of inexpensive and eco-friendly solar cells
