Ferroelectric materials have demonstrated novel photovoltaic effect to scavenge solar energy. However, most of the ferroelectric with wide bandgaps (2.7-4 eV) suffer from low power conversion efficiency less than 0.5% due absorbing only 8-20% spectrum. Instead harvesting energy, these can be well suited for photodetector applications, especially sensing near-UV irradiations. Here, a BaTiO3 film-based is that operated without using any external source and fast 405 nm light illumination...
