Abstract

In the present study, ZnO thin films are prepared successfully by simple and flexible spray pyrolysis technique on fluorine doped tin oxide glass substrate. The thermal spray deposition process is optimized by varying all the major parameters simultaneously: (1) precursor concentration; (2) substrate temperature; (3) carrier gas pressure; and (4) solution flow rate. Optical, structural and morphological properties are appropriately studied in detail. Most influencing parameters were observed to be the precursor concentration and substrate temperature, affecting film thickness, roughness, the band gap, and efficiency. It is confirmed that prepared films are uniform and crystalline in nature with a preferred orientation in (002) plane. The optical band gap is favourably in the range of 3.0–3.2 eV. At optimum conditions, the appropriate band gap (3.05 eV), thickness (89 nm) and roughness (2.38 nm) is achieved. The prepared films are consequently applied for perovskite solar cell preparation. Additionally, CuI (low-cost hole transport material) and carbon (counter electrode) are utilized. The efficiency of the device at optimum conditions is obtained to be maximum (3.21%). Maximum open circuit voltage (0.52 V), the maximum short circuit current (10.11 mA cm−2) and maximum fill factor (61%) is also achieved by the optimum device.
