This paper reports on the formation of a layered film and the highly improved photovoltaic output of the lead lanthanum zirconate titanate (PLZT) layer employed. The structural design is described using a top transparent indium tin oxide (ITO) electrode. The PLZT film exhibited V and µA output induced by light irradiation. The photovoltaic current of the PLZT film was more than 102 times larger than that of bulk PLZT, while the photovoltaic voltage per unit thickness in the layered film was almost the same as that in bulk ceramics and single crystals. These differences are due to the characteristics of the film and the configuration of the electrode. The PLZT film also has the advantage of easily controllable parameters: film thickness, illuminated area and illumination intensity. A simple model is used for the phenomenological explanation of the improved photovoltaic effect of the PLZT film.
