Scientists at IIT Create Low Cost Solar Cells using Jamun

Scientists at IIT Roorkee buy Indian summer fruit, Jamun, to make less costly plus much more efficient solar cells. To bring about the solar cells, the study widely used natural pigment evident in jamun as a reasonably priced photosensitizer for Dye Sensitised Solar Cells (DSSCs) or Gratzel cells. Gratzel cells aren't anything but thin film solar cells made from the porous layer of titanium dioxide (TiO2) coated photoanode, a layer of dye molecules that are designed for absorbing sunlight, an electrolyte for regenerating the dye, plus a cathode. Adore the look aspects of the Gratzel cell form a sandwich-like structure with the dye molecule playing an important role through its ability to absorb visible light.

Researchers widely used ethanol to extract the dyes from jamun. The extracted coloured pigment called anthocyanin was required to provide a sensitiser. The research got published inside Journal of Photovoltaics.

Significance

Natural pigments are cheaper attractive regular Ruthenium-based pigments to make solar cells. The research enjoy this assumes importance at the setting of increasing pressure on non-renewable fuels and concern about global warming. It'll likewise augment in realizing the country's vision to create up a 40% share of non-fossil fuel capacity inside power sector by 2030.
