Abstract : The photovoltaic effect and related processes in tetracene have been investigated. Experiments were made to measure the following: (1) photovoltaic i-v curve, the efficiency of tetracene is found to be about 0.0000007, (2) the polarization and the hysteresis due to an application of external field are observed, (3) the decay of the polarization takes in the order of seconds to minutes, and (4) the spectral dependence of the photovoltaic current, especially the anomalous behavior of the polarity reversal of the current. Theoretical work was to study the kinetics of decay of the charges and the polarization, and the polarity reversal of the photovoltaic current. This work implies the experimental observations are quite universal among organic semiconductors, and are not confined to tetracene. (Author)
