Abstract

The field of photovoltaics has evolved over the past few decades and introduction of quantum dots (QDs) have further improved their ability to absorb shorter wavelength radiations, which further attracted investigation on quantum dots. Among the QDs, zinc sulfide has shown remarkable results as a semiconductor. It is a low cost and a non-toxic material. Mn:ZnS is synthesized by a hydrothermal process and is characterized by UV–Visible spectroscopy to calculate the optical band gap (3.86 eV) and by X-ray diffractometer (XRD), particle size was calculated (40 nm) which was confirmed by scanning electron microscopy (SEM). Elemental analysis was carried out by energy dispersion spectroscopy (EDS) and X-ray photoemission spectroscopy (XPS). Here manganese is used as dopant to increase the luminescence property by red shift (587 nm), and thus, making a better candidate for photovoltaic applications. The ability of this material for photovoltaic application is evaluated by constructing a hybrid solar cell with P3HT and calculating the efficiency.
