The possibility of using polymer or organic films for photovoltaic or electret devices has been investigated by many investigators(1–5). In general, the open-circuit photovoltage in photovoltaic devices is much smaller than the potential difference across the energy gap of the materials if the mechanism responsible for the photovoltaic effects is due either to Schottky barrier, or to p-n junction...
It is well known that most fluids of low viscosity are penetrable into polyethylene and that some fluids such as acetophenone and silicone oil used as additives have the capability of inhibiting tree initiation or growth in polyethylene. Additives having such a capability are attractive to the insulation industry because the inhibition of tree initiation or growth implies the extension of the service...
