A photoresistor (also known as a photocell, or light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases resistance with respect to receiving luminosity (light) on the component's sensitive surface. The resistance of a photoresistor decreases with increase in incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in l… WebPhotoconductive cells are light-sensitive resistors in which resistance decreases with an increase in light intensity when illuminated. These devices consist of a thin single-crystal or polycrystalline film of compound semiconductor substances.
