  A SensL MicroFC-SMT-60035 6x6 mm$^2$ silicon photo-multiplier coated with a
NOL-1 wavelength shifter have been tested in the liquid xenon to detect the
175-nm scintillation light. For comparison, a Hamamatsu vacuum ultraviolet
sensitive MPPC VUV3 3x3 mm$^2$ was tested under the same conditions. The
photodetection efficiency of $13.1 \pm 2.5$% and $6.0 \pm 1.0$%,
correspondingly, is obtained.
