6 FAQs about [What are the parameters of photocells]
What is a photocell?
A photocell is a resistor that changes resistance depending on the amount of light incident on it. You might find these chapters and articles relevant to this topic. A photocell is a light-to-electrical transducer, and there are many different types available.
What is the sensitivity of a photocell?
The sensitivity of a photocell is defined as its resistance at a specific level of illumination. Since no two photocells are exactly alike, sensitivity is stated as a typical resistance value plus an allowable tolerance. Both the value of resistance and its tolerance are specified for only one light level.
What is the matching factor of a dual element photocell?
Likewise, for dual element photocells the matching factor, which is defined as the ratio of the resistance of between elements, will increase with decreasing light level. As the name implies, the dark resistance is the resistance of the cell under zero illumination lighting conditions.
How do photocells work?
Photocells are thin film devices made by depositing a layer of a photoconductive material on a ceramic substrate. Metal contacts are evaporated over the surface of the photoconductor and external electrical connection is made to these contacts. These thin films of photoconductive material have a high sheet resistance.
Why do photocells need a small series resistance?
Under such highly concentrated conditions and hence the existence of elevated current densities, the cells are required to have a sufficiently small series resistance so as to maintain an appropriately high fill factor; otherwise, photocells would suffer further undesired efficiency losses.
How does a photocell change its resistance?
A photocell or photoresistor is a sensor that changes its resistance when light shines on it. The resistance generated varies depending on the light striking at his surface. A high intensity of light incident on the surface will cause a lower resistance, whereas a lower intensity of light will cause higher resistance.
