In the present investigation, the recently developed, simple, robust, and powerful metaheuristic symbiotic organism search (SOS) algorithm was used for simulation of
J-
V characteristics and optimizing the internal parameters of the dye-sensitized solar cells (DSSCs) fabricated using electrospun 1-D mesoporous TiO
2 nanofibers as photoanode. The efficiency (
η =?5.80
%) of the DSSC made up of TiO
2 nanofibers as photoanode is found to be ~ 21.59% higher compared to the efficiency (
η =?4.77
%) of the DSSC made up of TiO
2 nanoparticles as photoanode. The observed high efficiency can be attributed to high dye loading as well as high electron transport in the mesoporous 1-D TiO
2 nanofibers. Further, the validity and advantage of SOS algorithm are verified by simulating
J-
V characteristics of DSSC with Lambert-W function.
