Abstract: The copper zinc tin sulphide (CZTS) alloy is a promising p-type earth abundant alloy that received profound attention as an electron driven dark catalyst in electrocatalytic reduction reaction. We report about fabrication of p-type CZTS film with the jet nebulizer assisted spray (JNS) coating technique. The electrocatalytic activity of the as-synthesized CZTS electrode is studied at tri-iodide reduction reactions and is tested as Pt-free electrocatalyst in proof-of-concept type device. Under identical experimental conditions the CZTS counter electrode- and platinum electrode-based dye-sensitised solar cells result similar photocurrent density of ∼ 10 mAcm-2. These results encourage applications of the aero-sol controlled spray coated CZTS films as the Pt-free electrocatalyst, where reduction reaction takes a key role in energy conversion and biosensing.
