Intrinsic photoresistor
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 … See more A photoresistor is less light-sensitive than a photodiode or a phototransistor. The latter two components are true semiconductor devices, while a photoresistor is a passive component that does not have a PN-junction. … See more • Optoelectronics • Photodetector See more Photoresistors come in many types.

WebAug 7, 2024 · The intrinsic photoresistor is made of un-doped pure semiconductor materials such as silicon or germanium. When Photons fall on the LDR then the semiconductor material’s excited electrons move from the valence band to the conduction band and the number of charge carriers are increased. WebMar 14, 2024 · Intrinsic photoresistor • This type of photoresistor is made with pure semiconductors without any doping. These are made of pure semiconductor materials such as silicon or germanium. When the incident light having an adequate amount of energy falls on this then electrons gain that energy and got excited and few of them go to the …
WebIntrinsic Photoresistor. Intrinsic Photoresistors (also known as a Photocell, light-dependent resistor, or photo-conductive cell LDR) are made using pure semiconductors only, and no doping is done while making them. The semiconductors which are used while making this kind of LDR are germanium and silicon. WebAn LDR or photoresistor is made up of a high resistance semiconductor having no P-N junction. Hence an LDR or photoresistor is a passive component. One such semiconductor material is cadmium sulphide or CdS. An LDR can either be made using intrinsic Semiconductors or extrinsic semiconductors. LDR made up of the former is called an …
