| Popis: | 31st European Photovoltaic Solar Energy Conference and Exhibition; 1333-1335 Oxygenated cadmium sulfide (CdS:O) thin films have been prepared by reactive RF magnetron sputtering with varying the O partial pressure from 0.08 mTorr to 0.18 mTorr. The quantitative results from the X-ray photoelectron spectroscopy (XPS) show that the relative concentration of oxygen atoms increases considerably with O partial pressure and O atoms are mostly combined with the S atoms to form SO4 complexes. The bandgap of the films were found in the range of 2.65 eV-2.74 eV.The film’s crytallinity was observed to reduce with the increase of O partial pressure. The complete cell was fabricated by sputtering technique with a novel configuration of ‘glass/FTO/ZnO:Sn/CdS:O/CdTe/Cu:C/Ag’. The performances of the ultra-thin cells (CdTe ~ 1μm) were evaluated under illumination of 1.5 AM, and the efficiency of 10.27% was achieved so far. |
