We present a study aimed at developing and optimising methods for ultra-cold neutron (UCN) detection using solid-state silicon detectors. For this we investigated the characteristics of neutron to charged particle converters (6Li, 10B) and compared different deposition techniques. We find that a deposition of 600 μg/cm2 of 6LiF is required to ensure maximum UCN detection efficiency using 6Li as converter. The UCN detectors that we have developed are now fully operational as a flux monitor and as a UCN spectrum analyser in the neutron electric dipole moment experiment at the Institut Laue Langevin in Grenoble.
