Abstract
|
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.
