Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting applications, high-power power conversion and other fields.
Photovoltaic applications
Semiconductor materials The photovoltaic effect is the basic principle behind the operation of solar cells. At this stage, the photovoltaic application of semiconductor materials has become a hot spot, and it is the fastest growing and well-developed clean energy market in the world. The main material of solar cells is semiconductor material. The main criterion for judging the quality of solar cells is the 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 are divided into crystalline silicon solar cells, thin film cells and III-V compound cells. 
Lighting application
LED is a semiconductor light-emitting diode built on a semiconductor transistor. Using LED technology, the semiconductor light source is small in size and can be packaged flat. It has low calorific value during operation, high energy saving and high efficiency, long product life, fast response, and is environmentally friendly and pollution-free. It can also be developed into thin, light and small products. Once it comes out, it will quickly become popular and become a new generation of high-quality lighting sources. It has been widely used in our lives. Such as traffic lights, backlights of electronic products, city night beautification light sources, indoor lighting and other fields, there are applications.
High-power power supply conversion
The mutual conversion of alternating current and direct current is very important for the use of electrical appliances and is a necessary protection for electrical appliances. This will use the power conversion device. Silicon carbide has high breakdown voltage strength, wide band gap, and high thermal conductivity, so SiC semiconductor devices are very suitable for applications with high power density and high switching frequency, and power conversion devices are one of them. Another performance of silicon carbide components at high temperature, high pressure, and high frequency makes it widely used in deep well drilling, inverters in power generation devices, energy converters for electric hybrid vehicles, and traction power conversion for light rail trains. Due to the advantages of SiC itself and the industry's need for lightweight, high-conversion-efficiency semiconductor materials at this stage, SiC will replace Si and become a widely used semiconductor material.
