Dye-Sensitised Solar Cells using Kamala Fruit

🔹 About:

Research team at Central University of Jharkhand has used the dye extract of the kamala fruit to create a low-cost and non-toxic sensitiser for dye-sensitised solar cells. 

🔹 Dye-sensitized solar cell:

1. It is a low-cost solar cell belonging to the group of thin film solar cells (converting solar energy into electricity).

2. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. 

3. The modern version of a dye solar cell, also known as the Grätzel cell

4. It is simple to make using conventional roll-printing techniques, is semi-flexible and semi-transparent which offers a variety of uses not applicable to glass-based systems, and most of the materials used are low-cost.

🔹 Grätzel Cells

1. Aka Regenerative Photoelectrochemical Cells

2. They convert sunlight energy into electric current but they do not store energy
