According to Taiwan’s “Economic Daily†report, Taiwan’s LED (light-emitting diode) industry leader Yiguang and Yifang Chemical’s investment in Yifang Energy Co., Ltd. set up Asia’s first concentrating solar energy demonstration power plant to be commercialized, which will lock Tainan. In the southern counties and cities of Taiwan, such as Kaohsiung and Pingtung, the planned power generation capacity is 1 megawatt. The first phase will build 200 kilowatts. It is estimated that the annual power generation will be 350,000 kWh, providing a new choice for clean energy.
It is understood that the oil price continues to rise, so that the solar industry has a hundred flowers, the current solar cell has three materials, one is the current mainstream crystalline silicon, mainly used in the family, but limited by material shortage, and conversion efficiency is low, about 17%.
In the new generation of solar cells, compound semiconductors and thin films are the most popular. The rapid blush of thin-film solar cells is due to the shortage of silicon materials. However, although the film is low in cost, it needs to be modularized, using thin-film solar modules. It is necessary to use a larger area and have a positive cooperation with the downstream plant.
As for the materials used in the space industry for the three or five concentrating multi-junctions, the efficiency is higher. However, because of the long time required for the sun, it is suitable for large power plants. These three materials can be estimated in different fields. The space they play.
At present, the island manufacturers that cross the three or five solar cells are almost all-in-one LED epitaxial factories. In addition to the new ones, there are also crystal and Huashang, mainly because its process is similar to that of LED epitaxial processes. Related equipment can be converted to production, and it is easy for the LED epitaxial plant to make a big investment without having to invest a lot.
In the past, we thought that the price of gallium arsenide in the three and five ethnic groups was high, and it is still to be observed that commercialization is still to be observed. However, after the first commercial power plant in Asia, the solar cells of the three and five ethnic groups have gone up.
LED heat waves rolling, please think twice!
