Introduction to solar cells
A solar cell is a device that uses the principle of photoelectric conversion to convert the sun's radiant light into electrical energy through semiconductor materials. This photoelectric conversion process is usually called the "photovoltaic effect", or "photovoltaic effect" for short. Therefore, solar cells are also called "photovoltaic cells". Simply put: when sunlight shines on the semiconductor material, it will cause the PN junction inside the semiconductor to move positive and negative electrons, thereby generating voltage.
The composition of solar cell components
• Toughened glass: the thickness is about 3 mm, and the light transmittance is above 90%;
• Solar cell: thickness is about 0.3mm, voltage is about 0.5V;
• Backplane: The protective material on the back of the battery panel, generally TPT, BBF, DNP, etc.;
• Junction box: Junction box is generally made of ABS, and added with anti-aging and anti-ultraviolet radiation agent;
• Aluminum alloy frame: It is made of hard aluminum alloy, and the thickness of the surface oxide layer is greater than 10 microns. It can be used for more than 25 years in the outdoor environment without being corroded and firm.
Characteristics of solar cells
Easy to install, low operating cost, low maintenance cost;
It can operate normally in a long-term unattended environment.
Working temperature: -30℃～95℃ Relative humidity: 0-99%
It has high photoelectric conversion efficiency and strong low light. It only needs to be used outdoors where there is direct sunlight.
Application areas of solar panels
1. Small home lighting system: household photovoltaic power generation system
2. Lamp power supply: such as garden lamps, street lamps, indoor lighting energy-saving lamps, etc.
3. Solar traffic lights: traffic lights, warning lights
4. Living areas: solar electric vehicles, solar water heaters, solar battery charging equipment
5. Communication/communication field: solar unattended microwave relay station, fiber optic cable maintenance station, broadcasting/ communication/ paging power system; rural carrier telephone photovoltaic system, small communication machine, soldier GPS power supply, etc.
6. Solar heating system: use solar energy to provide energy for the heating equipment in the room to heat it.
7. It is widely used in various lighting appliances, very suitable for electronic appliances and lighting in remote places such as villages, mountains, islands, highways and so on.
