What types of Nickel Hydride No. 5 battery are there and what are their applications?

　　Nickel Hydride No. 5 battery include monocrystalline silicon Nickel Hydride No. 5 battery, polycrystalline silicon Nickel Hydride No. 5 battery, amorphous silicon Nickel Hydride No. 5 battery, multi-compound Nickel Hydride No. 5 battery and many other types. They are widely used in solar power, transportation, communications/communications and other fields. Let’s introduce them in detail below. "Types and Applications of Nickel Hydride No. 5 battery".

　　1. Types of Nickel Hydride No. 5 battery

　　1. Monocrystalline silicon Nickel Hydride No. 5 battery

　　The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, with the highest reaching 24%. This is the highest photoelectric conversion efficiency among all types of solar cells at present. However, the production cost is so high that it cannot be widely used and widely used. commonly used. Since monocrystalline silicon is generally encapsulated with tempered glass and waterproof resin, it is strong and durable, with a service life of generally up to 15 years and up to 25 years.

　　2. Polycrystalline silicon Nickel Hydride No. 5 battery

　　The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower, and its photoelectric conversion efficiency is about 12%. In terms of production cost, it is cheaper than monocrystalline silicon solar cells. The material is easy to manufacture, saves power consumption, and the overall production cost is low, so it has been widely developed. In addition, the service life of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of performance-price ratio, monocrystalline silicon solar cells are slightly better.

　　3. Amorphous silicon Nickel Hydride No. 5 battery

　　Amorphous silicon solar cells are a new type of thin-film solar cells that appeared in 1976. They are completely different from monocrystalline silicon and polycrystalline silicon solar cells in manufacturing methods. The process is greatly simplified, silicon material consumption is very small, and power consumption is lower. Its main The advantage is that it can generate electricity even in low light conditions. However, the main problem of amorphous silicon solar cells is that the photoelectric conversion efficiency is low, the international advanced level is about 10%, and it is not stable enough. As time goes by, its conversion efficiency decays.

　　4. Multi-compound Nickel Hydride No. 5 battery

　　Multicomponent compound solar cells refer to solar cells that are not made of single element semiconductor materials. There are many varieties studied in various countries, and most of them have not yet been industrialized. The main ones are as follows:

　　a) Cadmium sulfide solar cells

　　b) Gallium arsenide solar cells

　　c) Copper indium selenide solar cell (new multi-band gap gradient Cu (In, Ga) Se2 thin film solar cell.

　　2. Application of Nickel Hydride No. 5 battery

　　1. User solar power supply

　　Small power supplies ranging from 10-100W are used for military and civilian life in remote areas without electricity, such as plateaus, islands, pastoral areas, and border posts, such as lighting, TVs, radios, etc.; 3-5KW household rooftop grid-connected power generation systems; photovoltaic water pumps, Solve the problem of deep water well drinking and irrigation in areas without electricity.

　　2. Transportation field

　　Such as navigation beacon lights, traffic/railway signal lights, traffic warning/sign lights, street lights, high-altitude obstacle lights, highway/railway wireless phone booths, unattended road shift power supply, etc.

　　3. Communication/communication field

　　Solar unattended microwave relay station, optical cable maintenance station, broadcast/communication/paging power supply system; rural carrier telephone photovoltaic system, small communication machine, soldier GPS power supply, etc.

　　4. Petroleum, ocean, and meteorological fields

　　Petroleum pipelines and reservoir gate cathodic protection solar power systems, oil drilling platform life and emergency power supplies, ocean detection equipment, meteorological/hydrological observation equipment, etc.

　　5. Home lighting power supply

　　Such as garden lights, street lights, portable lights, camping lights, mountain climbing lights, fishing lights, black light lights, rubber tapping lights, energy-saving lamps, etc.

　　6. Photovoltaic power station

　　10KW-50MW independent photovoltaic power stations, wind and solar (diesel) complementary power stations, various large parking plant charging stations, etc.
