Photosensitive resistance

MOKO Technology Ltd | Updated: Sep 17, 2015

Photosensitive resistance is also called light pipe, commonly used in the production of materials for the CDs, in addition to selenium, aluminium sulfide, lead sulfide and bismuth sulfide etc. materials. With these materials in light of specific wavelength characteristics, its resistance decreases rapidly. This is due to the light generated carriers are involved in conductive, in an applied electric field under the effect of the drift motion, electronic toward the power supply cathode, a hole toward the power anode, so that the resistance value of the photosensitive resistor decreased rapidly.
