Abstract
To improve the efficiency of the DSSC circuit, light absorption from organic dyes must reach the maximum visible and near infrared spectrum values. This research examined improvement of efficiency DSSC transparent by optimizing of Synthetic organic dye (5MSA). Synthetic organic dye in this research used Methyl salicylaldehyde with aniline. 5MSA dyes with optimized choice of agents indicated that improved photovoltaic impacts contrasted with organic dyes sensitization and increased the absorption of solar light and allowed utilization of the photon energy more efficienly. With using Doctor blade method coating, FTO glass with TiO2 as working electrode and opposite electrode used FTO glass with graphite. To determine the efficiency of DSSC for characterization of using Direct sunlight in different locations (Mayiladuthurai(L1),Nagapattinam(L2). Vedaranyam(L3)) using Digital multimeter and solar simulator using incandescent lamp with different glass plates.. The highest efficiency of the DSSC circuit is obtained direct sunlight from a combination of 5MSA which is equal to efficiency (η) reached 5MSA(L1-4.6% ;L2- 3.3% ;L3-4.4%) with an open circuit voltage (Voc) of (L1-32 V;L2-34V ;L3-39V), short circuit current density ( Isc) of (L1-100 mA;L2-80mA ;L3-60mA) with Fill factor (FF) of (L1- 1.46 ; L2-.1.21 ; L3-1.86). And the solar simulater reached miniumum and maximum lamp position with different glasses. In results 5MSA reached efficiency from frosted and plain glass with minimum and maximum lamp position, frosted glass with min and max lamp position reached efficiency η(Min-0.000012% ; Max-0.0002% ) and plain glass reached efficiency η(Min-0.00002% ;Max-0.0003%).
