Three Fresh Plant Seeds as Natural Dye Sensitizers for Titanium Dioxide Based Dye Sensitized Solar Cells

Sofyan A. Taya, Hatem S. El-Ghamri, Taher M. El-Agez & Monzir S. Abdel-Latif · Current Journal of Applied Science and Technology · 2014

In this paper, we used the extracts of three fresh plant seeds as photosensitizers for DSSCs based on TiO2 nanopowder as a semiconducting material. Ethanol was used to extract the dyes from the seeds. The fill factors of the cells sensitized with the seeds of Raphanus raphanistru...
