Abstract The paper presents the results of a study to identify the physical mechanism of anomalous photovoltage in polycrystalline structures. A qualitative theory of the effect of anomalous photovoltage is proposed on the basis of experimental results. In this work, the results an revealing the physical examination of the main photochemical polycrystalline structure's are brought. It is offered qualitative theory of the effect anomalous photochemical on base experimental result.
