Development and Investigation of Morphologically Tuned Tio2 Photo Electrode and Cu2znsns4 Counter Electrode for Dye Sensitized Solar Cell Application

Abstract

Dye sensitized solar cells (DSSC) have several advantages over conventional solar cells, such as eco-friendly, cost effective and very compact. DSSC has maximum theoretical power conversion efficiency (PCE) of 33 %. Recently, a record of photo conversion efficiency of greater than 12% has been achieved. The factors that normally affect the conversion efficiency of DSSC are: the nature of photo electrode, counter electrode, the absorption wavelength by dyes and redox potential of electrolytes. The choice of photo electrode (PE) and counter electrode (CE) is very much important, since they can directly affect the key properties of solar cell such as fill factor, incident photon to current conversion efficiency (IPCE) and photo voltage newline
