WebWhat is a Photoconductive cell? Photoconductive cells are light-sensitive resistors in which resistance is inversely proportionated to light intensity when illuminated. These devices … WebAll photoconductive cells exhibit a phenomenon known as hysteresis, light memory, or light history effect. Simply stated, a photocell tends to remember its most recent storage condition (light or dark) and its instantaneous conductance is a function of its previous condition. The magnitude of the light history effect depends upon the new light ...
WebAlthough this mode is faster, the photoconductive mode can exhibit more electronic noise due to dark current or avalanche effects. [5] The leakage current of a good PIN diode is so low (<1 nA) that the Johnson–Nyquist noise of the load resistance in a typical circuit often dominates. Related devices [ edit]
WebThe photoconductive gain can be substantially larger than unity, which means that the obtained photocurrent for a given light power (i.e., the responsivity) can be much larger than that of a photodiode. This is possible only because minority carriers reaching an electrode can lead to the injection of additional majority carriers; otherwise, an ...
