Optical Properties of Some Selected Fruit Juices and their Usage in Photovoltaic Cells as a Sensitizer

P. M. Sirimanne ^[2] | P. N. Dissanayake ^[2]

Abstract: Use of natural pigments in photo-electrochemical cells, as a sensitizer is a cost effective approach compare to that of ruthenium based metal centered dyes. Different pigments extracted from fruits were utilized as a sensitizer in solar cells. However, ruthenium based metal centered dyes exhibit much higher power conversion efficiency in dye-sensitized solar cells, due to excellent matching of band-gap with HUMO, LOMO levels of dye and charge transfer process.
