Dye sensitized solar cells (DSSCs) were fabricated using natural dyes extracted from Juglans Regia and Chamomile. To enhance performance of DSSCs based on natural dyes, we have devised efficient approach for extracting natural dyes including chlorophyll from Juglans Regia and Chamomile. The properties of extracted dyes have been investigated by UV-Vis technique. Solar cells sensitized by chlorophyll extracts from chamomile achieved up to JSC = 5.38 mA/cm2 and VOC = 0.42 V, while for Juglans Regia the values determined were up to JSC = 1.28 mA/cm2 and VOC = 0.32 V. The results obtained with extracts show a successful conversion of light into electricity by using natural dyes as sensitizers in DSSCs. It also represents an environmentally friendly alternative for DSSCs with low cost production and an excellent system for educational purposes.
