Semiconductors are materials whose conductivity is between conductor and insulator at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors. Semiconductors are of great importance both in terms of technology and economic development. The core unit of most electronic products (such as computers, mobile phones or digital recorders) is closely related to semiconductors. Let's take a look at the application fields of semiconductors.

1. The photoelectric effect of semiconductor materials is the basic principle of solar cells. At this stage, the photovoltaic application of semiconductor materials has become a hot topic, and the main manufacturing materials of solar cells are semiconductor materials. The main criterion for judging the quality of solar cells is photoelectric conversion rate. The higher the photoelectric conversion rate, the higher the working efficiency of solar cells. According to the different semiconductor materials used, solar cells can be divided into crystalline silicon solar cells, thin film cells and compound cells.
2. LED is a semiconductor light emitting diode based on semiconductor transistor. Using LED technology, the semiconductor light source is small in size and can be packaged flat. It has the advantages of low calorific value, energy saving and high efficiency, long product life, fast response speed and environmental protection. Pollution can also develop into light, thin and short products. Once it came out, it quickly became popular and became a new generation of high-quality lighting source. It has been widely used in our life. Such as traffic lights, backlight of electronic products, urban night landscape beautification light source, indoor lighting and other fields, all have applications.
3. The conversion between alternating current and direct current is very important for the use of electrical appliances, and it is the necessary protection of electrical appliances. This requires power conversion equipment. Silicon carbide has high breakdown voltage strength, wide band gap and high thermal conductivity. Therefore, semiconductor devices are very suitable for applications with high power density and switching frequency. Power replacement equipment is one of them. Another performance of silicon carbide assembly at high temperature, high pressure and high frequency makes it widely used in deep well drilling, inverter in power generation equipment, energy converter in electric hybrid vehicle and traction power conversion in light rail train.
