In the present study, we report the cost effective Pt and FTO-free (Cu2ZnSnS4 (CZTS) nanoparticle coated on W substrate) CE for ZnO-based DSSCs. Phase purity, the morphology and elemental composition of synthesized ZnO, CZTS nanoparticles and films were confirmed by physical characteristics such as XRD, FEG-TEM, and FEG-SEM respectively. Cyclic voltammetry study confirmed electrochemical catalytic activity of CZTS films. DSSCs fabricated with CZTS film on W and FTO substrate as CE exhibited efficiencies of 2% and 2.8%, respectively. Conventionally used Pt-based CE demonstrated an efficiency of 3.8 %.}, keywords = {Cu2ZnSnS4,thermal decomposition of metal precursors,tungsten (W),dye,sensitized solar cells,I,V characteristics,counter electrode.&nbsp}, url = {https://aml.iaamonline.org/article_14771.html}, eprint = {https://aml.iaamonline.org/article_14771_35ceecd34cc721ea48c6290e363436a5.pdf} }
