WebThis is called the photoelectric effect, meaning that light ( photo) produces electricity. One common use of the photoelectric effect is in light meters, such as those that adjust the automatic iris in various types of cameras. Another use is in solar cells, as you probably have in your calculator or have seen on a rooftop or a roadside sign. 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]
