The preparative parameters, (viz. growth temperature (56&deg;C), deposition time (80 minutes), reaction pH (11&plusmn;0.2) and the rate of mechanical churning (70&plusmn;2)) and deposition conditions were used as optimized previously. The electrode/electrolyte interfaces were then set up between the n-type Cd<sub>1-x</sub>Co<sub>x</sub>S (0 &le; x &lt; 0.5) photosensing electrodes and a sulphide/polysulphide (0.25 M ) redox electrolyte in H-shaped corning glass cells. A graphite rod treated in a cobalt sulphate solution for 24 hours was employed as a counter electrode. The as- fabricated cells were then characterized through the voltage-current and voltage-capacitance characteristics in dark, photovoltaic power output characteristics under constant illumination, and different responses of the cells to incident light. The PV performance parameters such open-circuit photopotential (V<sub>ph</sub>), short circuit photocurrent (I<sub>ph</sub>), series and shunt resistances (Rs &amp; R<sub>sh</sub>), efficiency (&eta;), form factor (ff), dark ideality factor (nd), ideality factor under illumination(nL), built-in potential (&Phi;<sub>B</sub>), dark current (I<sub>D</sub>), the flat band potential(V<sub>fb</sub>), junction capacitance under flat band condition (cj), cut off wavelength(&lambda;c) and photogenerated carrier life time(&tau;) were evaluated for various cells with a special emphasis given to the electrode composition (x). In general, photovoltaic output performance of the Cd<sub>1-X</sub>Co<sub>X</sub>S based electrochemical cell is improved after Co implantation (x=0.1) in CdS.</p><p>DOI: <a href="http://dx.doi.org/10.3126/jncs.v30i0.9387">http://dx.doi.org/10.3126/jncs.v30i0.9387</a></p><p><strong>Journal of Nepal Chemical Societ<em>y</em></strong></p> <p>Vol. 30, 2012</p> <p>Page: &nbsp;151-158</p> <p><strong>Uploaded date</strong>: 12/20/2013</p> <p>&nbsp;</p><p>&nbsp;</p> ER -
