A photodiode is a semiconductor device that converts light energy into electricity. When photons (particles of light) hit a photodiode, they generate photocarriers, which in turn form an electric current. The working principle of photodiodes is based on the photoelectric effect, that is, under the irradiation of light, electrons in the semiconductor material will be excited to form an electron-hole pair, and then form an electric current. Photodiodes usually operate in the reverse bias state, that is, the anode is connected to a positive voltage and the cathode is connected to a negative voltage. In the absence of light, the reverse current is very weak, while in the presence of light, the current will increase significantly.

In the medical field, photodiodes and light-emitting diodes also have a wide range of applications. For example, in applications such as heart rate and blood oxygen detection, infrared leds and photodiodes can be used to measure blood oxygen concentrations in the blood. This technology can not only realize non-contact measurement, but also has the advantages of high precision and low power consumption. In addition, photodiodes can also be used in fields such as photodynamic therapy and photothermal therapy, which use light energy to treat diseases and have the advantages of minimally invasive and low side effects.
