Photoelectric properties of polyphenylene sulphide

It has been shown experimentally by the transit-time method that the drift mobility of holes in polyphenylene sulphide is equal to approximately 10−4 cm2/V·sec and depends on temperature in accordance with an activation law. The introduction of electron-acceptor additions into the polymeric matrix somewhat reduces the mobility value but does not affect the activation energy. The dispersion transport of charged carriers is discussed within the framework of a model involving transfer with repeated capture in traps having a continuous distribution with respect to their energy. The possibility of sensitizing polyphenylene sulphide in the visible region of the spectrum has practical importance in connection with the fact that the photovoltaic effect is observed at the metal-polymer junction.
