What are the characteristics of photovoltaic cells and what are their applications?

　　Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. It is extremely refined, reliable, stable and has a long life. It can be applied to user solar power, transportation, communications/communications and other fields. It is introduced in detail below. Let’s take a look at “Characteristics and Applications of Photovoltaic Cells”.

　　1. Characteristics of photovoltaic cells

　　1. Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy.

　　2. Whether used independently or connected to the grid for power generation, the photovoltaic power generation system mainly consists of three parts: solar panels (components), controllers and inverters. They are mainly composed of electronic components and do not involve mechanical parts. Therefore, photovoltaic The power generation equipment is extremely refined, reliable, stable, long-lasting, and easy to install and maintain.

　　3. Theoretically, photovoltaic power generation technology can be used in any situation that requires power, from spacecrafts to household power supplies, from megawatt power stations to toys as small as toys. Photovoltaic power sources are everywhere.

　　The most basic component of solar photovoltaic power generation is solar cells (chips), including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film cells.

　　4. Currently, monocrystalline and polycrystalline batteries are used the most, and amorphous batteries are used in some small systems and calculator auxiliary power supplies. The efficiency of domestic crystalline silicon cells is about 10 to 13%, and the efficiency of similar foreign products is about 12 to 14%. A solar panel consisting of one or more solar cells is called a photovoltaic module.

　　2. Application of photovoltaic cells

　　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, mountaineering 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.
