Photoelectrochemical properties of spray deposited n-CdSe thin films
چکیده انگلیسی

Polycrystalline cadmium selenide (CdSe) thin films have been prepared by spraying a mixture of an equimolar aqueous solutions of cadmium chloride and selenourea on preheated fluorine doped tin oxide (FTO) coated glass substrates at different substrate temperatures. The cell configuration n-CdSe/1 M (NaOH + Na2S + S)/C is used for studying the capacitance–voltage (C–V) characteristics in dark, current–voltage (I–V) characteristics in dark and under illumination, photovoltaic power output and spectral response characteristics of the as deposited films. Photoelectrochemical study shows that as deposited CdSe thin films exhibits n-type of conductivity. The spectral response characteristics of the films at room temperature show a prominent sharp peak at 725 nm. The measured values of efficiency (η) and fill factor (FF) are found to be 0.50% and 0.44 respectively for film deposited at 300 °C. Electrochemical impedance spectroscopy studies show that the CdSe film deposited at 300 °C shows better performance in PEC cell.
