On April 12th, Oriental Semiconductor announced the official mass production of its high-voltage and high-speed MOSFET product – GreenMOS for electric vehicle charging piles, breaking the monopoly of foreign manufacturers in this field. This achievement has been covered by media outlets including People’s Daily：

Photovoltaic Applications

The photovoltaic effect of semiconductor materials is the fundamental principle behind the operation of solar cells. Currently, photovoltaic applications of semiconductor materials have become a major focus, representing the world’s fastest-growing and most dynamically developing clean energy market.
Semiconductor materials are the primary manufacturing component of solar cells. The key criterion for evaluating the quality of solar cells is their photoelectric conversion efficiency—a higher efficiency indicates greater operational performance of the solar cell. Based on the type of semiconductor material used, solar cells are categorized into three main types: crystalline silicon solar cells, thin-film solar cells, and III-V compound solar cells.

Lighting Applications

Light-Emitting Diodes (LEDs) are semiconductor light-emitting diodes based on semiconductor transistors. Semiconductor light sources using LED technology offer several advantages: they are compact, enabling flat-packaging; generate low heat during operation; are energy-efficient; have a long service life; and feature fast response times. Additionally, they are environmentally friendly (free of pollution) and can be developed into thin, lightweight, and miniaturized products.
Since their introduction, LEDs have rapidly gained popularity as a new generation of high-quality lighting sources and are now widely used in daily life. Typical applications include traffic signal lights, backlighting for electronic products, decorative lighting for urban nightscapes, and indoor lighting.

High-Power Power Conversion

The mutual conversion between alternating current (AC) and direct current (DC) is crucial for the operation of electrical appliances, serving as an essential protection measure for such devices. This conversion relies on power conversion equipment (e.g., inverters, converters).
Silicon Carbide (SiC) exhibits exceptional properties: high breakdown voltage, a wide bandgap, and excellent thermal conductivity. These characteristics make SiC semiconductor devices highly suitable for applications requiring high power density and high switching frequencies—power conversion equipment being a prime example.
SiC components also perform outstandingly under high-temperature, high-voltage, and high-frequency conditions, leading to their widespread use in fields such as deep-well drilling, inverters in power generation systems, energy converters for hybrid electric vehicles, and traction power conversion for light rail trains.
Due to SiC’s inherent advantages and the current industry demand for semiconductor materials that are lightweight and offer high conversion efficiency, SiC is expected to replace silicon (Si) and become the most widely used semiconductor material.
