7 Choice of photodiode materials A photodiode material should be chosen with a bandgap energy slightly less than the photon energy corresponding to the longest operating wavelength of the system. This gives a sufficiently high absorption coefficient to ensure a good response, and yet limits the number of thermally generated carriers in order to attain a low "dark current" (i.e.

Why Use Photocells? Photocells can provide a very economic and technically superior solution for many applications where the presence or absence of light is sensed (digital operation) or where the intensity of light needs to be measured (analog operation). Their general characteristics and features can be summarized as follows:
An example photocell is the Advanced Photonix PDV-P5002, shown in Figure 21.2 the dark, this photocell has a resistance of approximately 500 kΩ, and in bright light the resistance drops to approximately 10 kΩ.The PDV-P5002 is sensitive to light in the wavelengths 400-700 nm, approximately the same wavelengths the human eye is responsive to.

A typical CdS photocell characteristic curve is shown in Fig. 4. Its dark resistance is about five mega-ohms. This value falls to about 600 ohms at a light intensity of 100 lux, typical of a well illuminated room and to about 30 ohms at an intensity of 8000 lux, typical of bright sunlight. (The lux is the SI unit of illuminance produced by a ...
