| Abstract(in English) | High conversion efficiencies of up to 9.67% have been achieved using solar cells consisting of In_2O_3/CdS/CuInS_2 heterostructure. A Cu/In metallic precursor was annealed under H_2S atmosphere to form a CuInS_2 thin film. A KCN treatment, which removes leaky Cu_xS compound from Cu-excess CuInS_2 film, provides us with stoichiometric CuInS_2 films possessing excellent crystallinity and sufficiently low carrier concentration. A CdS buffer layer was formed from an iodide-containing chemical bath. The conduction band offset at this CdS/CuInS_2 interface is as small as 0.05eV, which is a suitable value for solar cells applications raising the open circuit voltage up to 717meV. |
