Özet:

 

The present paper examines the effects of surface modification of CdS with diverse dyes on fabricated CdSbased  hybrid solar cells. The X-ray diffraction results showed that CdS thin films had a hexagonal phase with a preferred  orientation along the (101) plane. Scanning electron microscopy indicated that the CdS specimen was composed of a  granular structure while a P3HT layer was formed from tiny grains. Band gaps of the CdS thin films and the P3HT layer  were 2.45 eV and 1.98 eV, respectively. The absorption spectra showed that different dye loading caused an increase in  the absorbance of CdS thin films in the wavelength range of 400-650 nm. The photoluminescence of the CdS/P3HT  structure including various dyes was lower than that of the pristine one, implying that efficient charge separation was  achieved upon surface modification. Current density-voltage curves showed that the ITO/CdS/N719/Ag hybrid solar  cell exhibited the best overall efficiency of 0.082%, which can be attributed to improvements in both short circuit current  density (Jsc) and open circuit voltage (Voc) . These enhancements can be attributed to the creation of better interfacial  contact between CdS and P3HT layers after dye loading.
