Dye-Sensitized Solar Cells (DSSCs) Based on Extracted Natural Dyes [PDF]

Journal of Nanomaterials, 2019
Here, three natural dyes were extracted from different fruits and leaves and used as sensitizers for dye-sensitized solar cells (DSSCs). Chlorophyll was extracted from spinach leaves using acetone as a solvent. Anthocyanin was extracted from red cabbage and onion peels using water.

Dye molecules in electrolytes: new approach for suppression of dye-desorption in dye-sensitized solar cells [PDF]

, 2013
The widespread commercialization of dye-sensitized solar cells remains limited because of the poor long-term stability. We report on the influence of dye-molecules added in liquid electrolyte on long-term stability of dye-sensitized solar cells.
