제목 Wet Chemical Synthesis of SnS2 Nanoparticles for Thin Film CIGS Solar Cell Application
초록 Currently, as an alternative buffer layer to the toxic cadmium sulfide (CdS), the tin disulfide (SnS2) has been investigated due to its suitable wide band gap (~2.9 eV) to transmit most of the solar light spectrum to the Cu(In, Ga)Se2 light absorber. In addition , the SnS2 consists of low-cost, earth abundant, and non-toxic elements. This work presents the successful synthesis of SnS2 nanoparticles using a facile chemical precipitation method. The X-ray photoelectron spectroscopy (XPS) results showed that synthesized SnS2 nanoparticles has a stoichiometric composition of Sn and S. The Raman spectroscopy has showed a characteristic peak at 316 cm-1 that corresponding to the hexagonal SnS2 phase. The calculated band gap energy from absorbance spectra of SnS2 film is found to be ~2.8 eV. The fabricated CIGS device with SnS2 as buffer showed the conversion efficiency (~5%) close to the efficiency (~7%) of device fabricated with CdS as reference buffer layer.
