• The increase of photocurrent by a superposition of DC voltage, which is remarkable only in powdered CdS, is phenomenologically discussed with an equivalent circuit. The photoconductance in powdered CdS is obtained from the AC photo-admittance at frequencies higher than 30 kHz, and is estimated to be 1.3×10^<-5> mho/cm^2 at a light intensity of 100 μW/cm^2. The DC photocurrent is influenced largely by interparticle barriers which show the Schottky effect. The AC photoconductance in the presence of a DC voltage is well explained in terms of an equivalent circuit containing barrier-resistance. Similar frequency characteristics to the case of the superposition of a DC voltage are observed on the application of a large AC voltage. It seems that the apparent increase of the photo-admittance in the above case is due to the decrease of the interparticle barrier-resistance.
