Jun-July 2013 EDITION Comparative Performance of Dye Sensitized Solar Cells Using Two Electrolytes

Abstract: Dye-sensitized solar cells (DSSCs) as a low price photovoltaic technology have attracted widespread attention in recent years. They have shown the impressive power conversion performance and are promising candidates for low-cost photovoltaic devices. The electrolytes typically used in these cells are usually containing iodide/triiodide redox couple in organic solvents. The aim of this work is to study the performance of DSSC experimenting with different electrolytes. DSSCs are fabricated using two electrolytes viz. potassium iodide and solution of iodide and iodine. Graphite is used as a counter electrode and natural dye extracted from hibiscus is used as a sensitizer. Comparative performance of DSSCs for two electrolytes in terms of performance parameters are found out and studied
