Abstract This paper gives a detailed description of the design and synthesis of some organic and inorganic sensitizers for DSSC’s. Five organic and inorganic dyes were used as sensitizers to fabricate DSSC’s. Fresh extracts of different organic and inorganic materials were used as sensitizers in the DSSC’s. The organic and inorganic dyes which are used are Beet Root, Fig, Ruthenium, Ruthenium Chloride and Blue Dye. The photo-electrochemical measurements for these DSSC’s indicate the variation in open circuit voltage (VOC) from 400 mV to 621 mV, and that in short circuit current density (JSC) ranges from 1.312 mA/cm2 to 12 mA/cm2. Ruthenium sensitizer shows maximum value of VOC (621 mV). The photo-to-electric conversion efficiency of Ruthenium based DSSC is found to be 3.86%.
