最近在铁电材料中发现的反常光伏效应引起了铁电和固态物理专家的极大关注。该效应的反常性质表现为在铁电和热释电材料中产生的光电动势比带隙大许多个数量级，可达103-105V。铁电体中的反常光伏效应在体相全息术中得到了广泛的应用。本文综述了铁电材料中反常光伏效应的实验研究，以及为解释这一效应而提出的各种模型。
The recently discovered anomalous photovoltaic effect in ferroelectrics is attracting considerable attention of specialists in ferroelectricity and solid-state physics. The anomalous nature of the effect is manifested by the fact that the photo-emf developed in ferroelectrics and pyroelectrics is many orders of magnitude greater than the band gap and can reach 103–105V. The anomalous photovoltaic effect in ferroelectrics has found extensive applications in volume phase holography. A review is given of the experimental investigations of the anomalous photovoltaic effect in ferroelectrics and also of the models proposed to explain this effect.
