Solar street lamps electro-thermal conversion principle is what

Compound semiconductor is normally composed of two or more substances, and he has a lot of, the characteristics of composition and structure is very complicated, which can lead to the production of single crystal is difficult, and compound semiconductor is the key of the current research in semiconductor industry.

normal compound semiconductor is composed of two or more substances, and he has a lot of, the characteristics of composition and structure is very complicated, which can lead to the production of single crystal is difficult, and compound semiconductor is the key of the current research in semiconductor industry. Is the basis for the street light industry production, because they have been used in the manufacture of LED street light lamp holder to a lot of semiconductor.

manufacture LED street lamp head and planar transistor, integrated circuits, you first need to generate the substrate ( Or substrate) And then on the substrate using extension method ( Such as liquid phase epitaxy, vapor phase epitaxy, molecular beam epitaxy or metal organic chemical vapor deposition extension, etc. ) Made of p-n junction, again through the process such as chip making, encapsulation, finally made a qualified LED street light. LED street lamp head substrate material and extension are used compound semiconductor.

especially developing countries and regions. Owning to the shortage of conventional energy is generally so looking for alternative energy sources, the first is the solar energy research and development, especially the solar energy heat utilization.

solar energy through heat energy is converted to electricity class, this process can be directly converted into electrical energy by heat, such as solar street light. Also can be indirectly converted to electricity by the heat. The former includes thermoelectric power conversion and thermal ion effect, etc. The latter includes the use of water or other liquid and air as working medium temperature. But whether direct or indirect process, they were given a carnot engine efficiency.

solar electricity use. Can be classified according to different USES for a variety of different. As solar street light, because of the different purposes, the kinds and properties of solar cells used can have bigger difference.

solar cell is a semiconductor photoelectric device on the other hand. It can convert light energy directly into electricity. Thus it can be as a energy converter using; On the other hand. It also can change light signals into electrical signals of corresponding change. And therefore can be used as a photoelectric signal converter.

people reach the surface of the earth using the light of the sun radiation energy on a thermal conversion process and production services for the life, history is very long, and is also very extensive. So far, solar street light and solar heat utilization is still the most mature technology, high conversion efficiency in solar energy utilization, the price is relatively cheap one aspect; Especially in the low temperature heat utilization, due to the heat source and heat load grade is low, both from efficient use of energy, is the most economic and reasonable.

is too old to large-scale use, is mainly used to generate electricity. Solar power has two ways, one is a light hot electricity conversion mode, the other one is light electricity transformation way directly.
