    • Abstract


      Photoconductivity of polystyrene doped with anthracene as a donor and 7,7,8,8-tetracyanoquinodimethane as acceptor was investigated by studying the photocurrent (Iph), the dark current (Id) and the sensitivityIph/Id as the acceptor concentration changed. For this purpose a novel liquid cell was designed and successfully used for measurements. It was found that polystyrene films containing (1∶10) donor-to-acceptor ratio has the greatest sensitivity as the applied charging voltage equals 0·25 volt.
