Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting applications, high-power power conversion and other fields.

Photovoltaic (pv) application

The photovoltaic effect of semiconductor materials is the basic principle of solar cell operation. At present, the photovoltaic application of semiconductor materials has become a hot topic, which is the fastest growing and the best developing clean energy market in the world. The main production material of solar cells is semiconductor material. The main standard to judge the merits of solar cells is the photoelectric conversion rate. The higher the photoelectric conversion rate, the higher the working efficiency of solar cells. Depending on the semiconductor materials used, solar cells are divided into crystalline silicon solar cells, thin film cells and III-V compound cells.

Lighting applications

LED is built on semiconductor transistor semiconductor light-emitting diode, the LED semiconductor laser source volume is small, can realize planar encapsulation, low calorific value, energy conservation and efficient at work, long product life, fast response, and green environmental protection no pollution, also can develop into a lightweight products, and as it comes to the is quickly spread, Become a new generation of high-quality lighting source, has been widely used in our life. Such as traffic lights, electronic backlight, urban night landscape landscaping light source, indoor lighting and other fields, have been used.

High power conversion

Alternating current and direct current conversion is very important for the use of electrical appliances, is the necessary protection of electrical appliances. This is the use of the power conversion device. Silicon carbide breakdown voltage strength is high, wide band gap width, high thermal conductivity, so SiC semiconductor devices are very suitable for application in the power density and high switching frequency occasions, power conversion device is one of them. Silicon carbide components in high temperature, high pressure, high frequency performance makes it is now widely used in deep well drilling, power generation equipment in the inverter, electric hybrid vehicle energy converter, light rail train traction power conversion and other fields. Due to the advantages of SiC itself and the current industry needs for lightweight, high conversion efficiency semiconductor materials, SiC will replace Si and become the most widely used semiconductor materials.
