We report the optical transmission spectrum of cerium and samarium oxide films, and the use of these materials as antireflective coatings on silicon photoelectronic transducers. It is shown that the oxide films exhibit high transmission in the 400-1200 nm spectral region and make it possible to reduce the reflection coefficient from the silicon surface to 1.2-1.9%, and the integrated reflection coefficient for radiation in the range 400-1000 nm may be reduced to 8-9%. It is shown that an antireflective coating of cerium or samarium oxide increases the short circuit photocurrent from silicon photoelectric devices by more than 40%.
