Correction to: Synthesis and characterization of ZnO nanoparticles and their application in dye‑sensitized solar cells

Simple and easy synthesis of ZnO nanoparticles is done using Zinc metal dust and double distilled water. ZnO nano-powder is synthesized by using two methods: reflux (ZnO) and hydrothermal methods (ZnO-24 h. and ZnO-48 h.) using Zinc metal dust as a precursor. Photoanode plays an important role in dye-sensitized solar cells, a compact layer is included via the SILAR method to reduce the recombination. The hydrothermal synthesis is carried out at two different temperatures. Results show that ZnO powder has a wurtzite crystalline structure with a band gap of 3.2 eV. Here these powders are further used to fabricate Dye-Sensitized Solar cells. From J-V characteristics the short circuit current for ZnO was 1.88 mA cm −2 , Voltage was observed to be 0.54 V, fill factor was observed to be 0.48, and Efficiency was observed to be 0.5%. The various other parameters such as chronoamperometry, chronopotentiometry, and Electrochemical Impedance spectroscopy supporting the J-V characteristics were also studied. The external quantum efficiency very well supports the optical absorption spectra of the N3 dye.
