It was found that sensitization time had a strong effect on the main performance parameters. the best photovoltaic performance was achieved after sensitization for 36 h (short circuit current density, 5.41 mA cm(-2); overall conversion efficiency, 3.42%). Computational UV-Vis absorption spectra of the molecule was calculated using time dependent density functional theory and was found consistent with measured UV-Vis spectra.en10.1515/hc-2020-0007info:eu-repo/semantics/openAccessmetallophthalocyaninecarboranephotovoltaicdye-sensitized solar celldensity functional theoryArticle2613745WOS:0005255806000012-s2.0-85083644981Q3Q4
