It is generally acknowledged that the breaking of inversion symmetry is essential for the existence of an anomalous photovoltaic (APV) effect. In article number 1801619, Yongxiang Li, Zhiguo Yi, and co‐workers report the discovery of an APV effect in a centrosymmetric vanadate, where noticeable above‐bandgap photovoltage and steady‐state photocurrent are observed even when illuminated under visible light.

异常光伏：中心对称铁弹性BiVO4中的异常光伏效应（Adv。Mater。44/2018）

通常公认的是，反转对称性的破坏对于异常光伏（APV）效应的存在至关重要。李永祥，易志国及其同事在文章1801619中报告了在中心对称钒酸盐中发现APV效应的发现，即使在可见光下也观察到了明显的带隙以上光电压和稳态光电流。
