Different from the semiconductor photovoltaic device on the basis of an interfacial effect, UV detection was realized in this letter by using bulk photovoltaic mechanism involving the depolarization field in a W-doped Pb0.97La0.03(Zr0.52Ti0.48)O3 (PLWZT) ferroelectric thin film. A prototype of UV detector was demonstrated in the laboratory as well as under sunlight, in which the ferroelectric PLWZT thin film was polarized in the plane of the film surface. Characteristics of the photovoltaic response of the ferroelectric thin films and their application values for UV detection were analyzed.
