<p>A photovoltaic UV detector configured to generate an electrical output under UV irradiation. The photovoltaic UV detector comprises a first layer comprising an electrically polarized dielectric thin layer configured to generate a first electrical output under the UV irradiation; and a second, layer configured to form an electrical energy barrier at an interface between the second layer and the first layer so as to generate a second electrical output under the UV irradiation, the second electrical output having a same polarity as the first electrical output, the electrical output of the photovoltaic UV detector being a sum of at least the first electrical output and the second electrical output. The electrically polarized dielectric thin layer may be a ferroelectric thin film, which may comprise PZT or PZLT. The second layer may be a metal and the electrical energy barrier may be a Schottky barrier.</p>
