The photoelectret property of a high-density polyethylene (HDPE)-semiconductor (n-InSe) composite is investigated. It was found that the magnitude of the photoelectret potential non-monotonically depends on the n-InSe content. Treatment under the action of an electric discharge plasma in an electronegative gas significantly affects the magnitude of the photoelectret potential and its dependence on the content of the semiconductor filler in the composite. It is shown that in the considered case the main source of electric charge generation is the filler, and in the process of polarization the determining one is the electric field at the polymer-semiconductor interface. This composite is promising for optoelectronics.
