| dc.description.abstract | Kesterite materials show excellent optical and semiconductive properties for use as petype absorber
layer in photovoltaic (PV) applications, but they have a high open circuit voltage deficit (Voc,def) due to
high antisite defect and secondary phase formation, resulting in poor device performance. This work
reports a PV cell composed of Cu2PdSnS4 (CPTS) nanoparticles as an absorber layer yielding highly
improved Voc of 900 mV, which is two times that of fabricated pristine Cu2ZnSnS4 (CZTS) PV cell.
Improved PV cell parameters such as fillefactor (FF) of 83.4% and power conversion efficiency (PCE) of
1.01% were obtained for CPTS devices which are 3efold that of pristine CZTS devices. Optical studies
revealed enhanced redshift absorption for CPTS nanoparticles. Electrochemical studies show improved
current production, high electron mobility and low charge resistance for CPTS nanoparticles. This study
shows that the improved photovoltaic properties can be attributed to enhancement in the bulk properties when Zn atoms are replaced by Pd atoms in kesterite nanomaterials as absorber layer material for
PV applications. | en_US |
