Packaging and manufacturing process of ground solar cell module
The role of solar cell assemblies
Applications of solar cell modules
Standard Specification for solar cells
Solar cells are generally divided into the following specifications:
Isc (A), Imp (A), Voc (V), Vmp (V)
The thickness of 103 * 103 (mm2) is generally 250-350, 3.2, 2.96, 0.6, 0.48
125 * 125 (mm2)
Five
Four point six three
Zero point six
Zero point four eight
150 * 150 (mm2)
Between microns.
Seven point two
Six point six six
Zero point six
Zero point four eight
Fill factor 74%
Why encapsulation?
Prevent damage to solar cells; prevent solar cells from corroding;
Meet the load requirements in series or in parallel into one
Independent enough to be used as the smallest unit of power supply.
Solar cells need encapsulation
Solar cells are easy to break
Crystalline silicon is brittle
Silicon solar cells have large area and small thickness of silicon solar cells
Solar cells are brittle!!!
Solar cells need encapsulation
The natural resistance of solar cells is poor
Solar cells are exposed to air for long periods of time, and their efficiency is attenuated
Solar cell poor resistance to UV? Solar cell can not resist the excessive mechanical hail caused by external force caused by stress damage? Metal layer on the surface of the solar cell is susceptible to corrosion? Solar cell surface accumulation of dust is difficult to remove
Solar cells need encapsulation
Unit power of solar cell
The output power of solar cells is as follows:
Specifications
Pmp 1.43W
2.11W
13.5%.
13.5%
103 x 103 (mm2) 125 * 125 (mm2)
150 * 150 (mm2)
3.04W
13.5%
Since the output power of single chip solar cells is difficult to meet the demand of conventional power supply, they need to be connecte
