Abstract
In the present study, effect of annealing in Al/nanostructured porous silicon multilayer (PS-ML): p+-Si Schottky photovoltaic device is observed for the behavioural change in its pyro-phototronic and corresponding photovoltaic effect. Under UV (365 nm) illumination condition, the as-prepared device shows maximum enhancement and increment factor of 31.16% and 186% at \(0.5V\) compared to the devices annealed at temperatures \(50^\circ C\) and \(100^\circ C\) respectively. 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 to \(150^\circ C\), the pyro-phototronic effect diminishes while photovoltaic is still retained. 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. While on elevating the annealing temperature to \(200^\circ C\), device performance degrades.
