Difference between photoemissive photoconductive and photovoltaic transducer
Answers
The difference between these two classifications is that photoconductive detectors use the increase in electrical conductivity resulting from increases in the number of free carriers generated when photons are absorbed (generation of current), whereas photovoltaic current is generated as a result of the absorption of photons of a voltage difference across a p-n junction (generation of voltage).
In general, photoconductive detectors have a higher frequency response, however they also have a higher signal to noise ratio. We recommend using photoconductive detectors if you are using a high-powered laser.
The distinction among these two classes is that photoconductive detectors utilize the increment in electrical conductivity occurring from advances in the number of available carriers formed when photons are incorporated production of current, whereas photovoltaic course is formed as a consequence of the reception of photons of a charge variation across a p-n junction (production of voltage).
In general, photoconductive detectors have a greater recurrence response, however, they also have a greater sign to sound ratio. We suggest utilizing photoconductive indicators if you are utilizing a high-powered laser.
