| Abstract: | Anomalous but weak photovoltaic effect has been observed in the case of thin polycrystalline ZnTe films obliquely deposited on glass substrate. Photovoltage of the order of a few hundred millivolt per centimeter have been observed at the ambient temperature. Optimized conditions for growing films to obtain maximum photovoltage have been found. In order to explain the observed photovoltaic effect, a model comprising of a long chain of aligned microcells in the form of p p+ homojunctions has been proposed. The implications are discussed. |
