Zinc selenide and Mn doped ZnSe nanoparticles were synthesized by solvothermal method. The synthesized nanoparticles were characterized by XRD, UV, PL, SEM and EDX spectral analysis. X-ray diffraction analysis confirmed a hexagonal wurtzite structure and the grain size were found to be 19.32 nm and 7.95 nm for pure and Mn doped ZnSe nanoparticles. The band gap energy was computed from the absorption data as 2.3 eV for ZnSe nanoparticles and 3.4 eV for Mn doped ZnSe nanoparticles. The EDX spectral analysis confirmed the purity of the samples. The solar cell was fabricated using TiO2 as a photoanode, pure and doped ZnSe as a counter electrode, ruthenium dye as sensitizer and I-/I3- as electrolye and the maximum conversion efficiency of solar cell were found to be 3.21%.
