Effect of dimethyl borate composition on the performance of boron doped ZnO dye-sensitized solar cell (DSSC)

Effect of dimethyl borate (C 3 H 9 BO 3 ) composition on the structure, morphology, thickness, elemental composition, optical absorption, photoluminescence of ZnO nanotubes and the performance of the DSSC has been studied. It was found that the structure, diameter, thickness, elemental composition, optical absorption and morphology of ZnO nanostructure are significantly influenced by the composition of dimethyl borate. The diameter and thickness of ZnO nanotubes decrease with the increase in the composition of C 3 H 9 BO 3 . The photoluminescence increases with the composition of C 3 H 9 BO 3 . The DSSC utilizing ZnO nanotubes synthesized at 1 wt% C 3 H 9 BO 3 yields the J SC and η of 1.9 mA cm −2 and 0.222 %, respectively.
