An evaluation system 1 according to the present invention includes: a light source 2 for exposing a pulsed white light or a pulsed laser light onto a sample; a microwave exposing and detecting unit 8 for exposing a microwave onto an organic material 12 and for detecting the intensity of the microwave which has passed through the organic material 12; a microwave passing unit 7 for making the microwave pass through the organic material 12 a plurality of times; and an evaluating unit 10 for evaluating the photoelectric conversion characteristics of the sample based on the intensity of the microwave which has passed through the organic material 12 when the pulsed white light or the pulsed laser light is exposed and the intensity of the microwave which has passed through the organic material 12 when the pulsed white light or the pulsed laser light is not exposed.
