In the present study, effect of annealing in Al/nanostructured PS-ML: p+-Si Schottky photovoltaic device is observed for the behavioural change in its pyro-phototronic and corresponding photovoltaic effect. Under UV (365nm) illumination condition, as prepared device shows maximum enhancement and increment factor of 31.16% and 186% at \(0.5V\) compared to the devices annealed at temperature \(\ge 50^\circ C\). However, the coupling between pyro-phototronic and photovoltaic effect remains effective only for the device annealed up to \(100^\circ C\). On further elevating the annealing temperature, the pyro-phototronic effect diminishes while photovoltaic effect remains. The device treated at \(150^\circ C\) shows enhancement in open circuit voltage (\({V}_{oc}\)) value of \(\pm 841 mV\) with large value of fill factor (FF) of \(27\%\) and power conversion efficiency (PCE) of \(9.63\%\) and \(6.36\%\) for upward and downward poling respectively.

Polycrystalline zinc oxide (ZnO) thin films were deposited on soda-lime glass substrates using the chemical spray pyrolysis method at three different substrate temperatures: 400, 450, and 500 °C. The solvents used in the precursor solution consisted of either ethanol or methanol. The effects of these solvents on the compositional, structural, morphological, electrical, and optical properties were studied with different techniques, including Rutherford Backscattering Spectrometry (RBS), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), four-point method, and Ultraviolet and Visible Spectroscopy (Uv-Vis). The results show that both temperature and the type of solvent modify the properties of the materials. An essential outcome of the study was that at 500 °C, the ZnO thin films prepared with either ethanol or methanol exhibited almost the same high-quality crystallinity, stoichiometry, average crystallite size, energy band gap, and resistivity. These findings contribute to our understanding of the properties of these materials and their potential applications.
