Abstract

Antimony selenide (Sb2Se3) attracted as potential candidate as absorber for photovoltaic application. Antimony selenide for self-powered photodetection and counter electroded dye sensitized solar cell remnant unexplored much. Herein, device grade nanowire Sb2Se3 film is developed through solution process spray coat method, studied its light traction and solar cell application. The developed photodetector shown responsivity of 1.5 μA/W, specific detectivity of 6.5×108 Jones and ultra-fast response speed with rise time of 250 ms, decay times of 670 ms. Antimony selenide based counter electrode based dye sensitized solar cell witnessed 4.18 % of power conversion efficiency (PCE).
