An experimental approach for the direct measurement of the circular photocurrent (CPC) has been developed. The method was tested for the measuring the CPC due to photon drag effect in the Ag/Pd nanocomposites film in a wide spectral range. Measurements were performed at the wavelengths of 266, 532, and 1064 nm. The experimental results were compared with those obtained by the indirect conventional scheme. The obtained results open a new possibility of application of the Ag/Pd nanocomposites film to determine the direction of the electric field vector rotation of elliptically polarized light.
