Description
Summary:In this work, the response surface methodology (RSM) has been applied to optimize the process parameters in the preparation of polymer composite which is used as an electrolyte in dye sensitized solar cell (DSSC). Optimisation of two different parameters such as percentage doping of vanadium pentoxide and conductance of the polymer composite has been presented for preparation of polymer composite. These parameters do effect the efficiency of the DSSC and it has been evaluated using ANOVA results of polynomial regression. The results showed that the value of R2 and adjusted R2 are 0.9894 and 0.9818 respectively, which is quite high. Furthermore, there was good agreement between predicted and experimental values of efficiency. The iodine and indium free environmentally benign DSSC fabricated using vanadium pentoxide doped polyaniline as electrolyte resulted in high fill factor (ff) of 58.3 %, open circuit voltage (VOC) of 799 mV, short circuit current (ISC) of 29.3 mA with 3.62 % efficiency.
