I. San 'an Photoelectricity
Sanan Optoelectronics is a "national high-tech industrialization demonstration project" approved by the National Development and Reform Commission and a "leading enterprise in semiconductor lighting engineering" recognized by the Ministry of Science and Technology and the Ministry of Information Industry. Mainly engaged in the research and development, production and sales of full color ultrasound high brightness LED epitaxial wafers, chips, III-V compound semiconductor materials, microwave communication integrated circuits, power devices and optical communication components. The company was established in June 2000, 1 1. Located in the beautiful Ludao Xiamen, it is the domestic production base of full color ultrasound high brightness LED epitaxy and chip industrialization.
Second, photovoltaic.
1. Photovoltaic: short for solar power generation system. It is a new type of power generation system that directly converts solar radiation energy into electric energy by using photovoltaic effect of semiconductor materials of solar cells. There are two modes of independent operation and grid-connected operation. At the same time, solar photovoltaic power generation system is classified as centralized, such as large-scale northwest ground photovoltaic power generation system; One is distributed (bounded by >: 6MW), such as photovoltaic power generation system on the roof of industrial and commercial enterprises and photovoltaic power generation system on the roof of residential buildings.
2. Photovoltaic panel module is a kind of power generation device that generates direct current under sunlight irradiation, and it is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Because there are no moving parts, it can run for a long time without any loss. Simple photovoltaic cells can provide energy for watches and calculators, while more complex photovoltaic systems can provide lighting for houses and power for power grids. Photovoltaic panel modules can be made into different shapes, and the modules can generate more electricity when connected. Photovoltaic panels are used on roofs and building surfaces, and even as a part of windows, skylights or shielding devices. These photovoltaic facilities are usually called photovoltaic systems attached to buildings.
Third, the advantages of photovoltaic power generation
(1) there is no danger of failure;
(2) Safe, reliable, noise-free and pollution-free, and absolutely environmentally friendly (pollution-free);
(3) it is not limited by the geographical distribution of resources, and it is beautiful to install on the roof of a building;
(4) local power generation and power supply can be realized without consuming fuel and erecting transmission lines;
⑤ High energy quality (at present, the highest conversion rate in the laboratory has reached more than 47%);
⑥ Users are easy to accept and love emotionally;
⑦ The construction period is short, and the time required for obtaining energy is short;
From the perspective of national security, photovoltaic power generation can achieve family self-sufficiency and avoid the devastating blow brought by war.
