The authors regret to inform the readers that Eqs. (11) and (12) have typographical errors, where the product of the open circuit voltage (Voc) and the short circuit current (Isc) is divided by the fill factor (FF) instead of being multiplied. The equations should read as follows: [Formula presented] [Formula presented] In the actual calculation which followed, the FF was multiplied not divided and accordingly all the graphs were drawn. So the results presented in the graphs, the discussions and conclusions still remain the same and require no change. The authors would like to apologise for any inconvenience caused.
