How big is a single solar cell?

Introduction The size of a single solar cell depends on its volume or surface area. The size of the 125 battery is 125mm x 125mm. Due to chamfering, the single crystal has a small chamfering area.

How big is a single solar cell?

Are you asking about volume or surface area?

The size of the 125 battery is 125mm x 125mm. Due to the existence of chamfers,

The small chamfer area of ​​the single crystal is 14,857 square millimeters

p>The large single crystal The chamfer area is 15481 square millimeters

The size of the 156 battery is 156mm*156mm, also because the chamfer area

The area of ​​the single crystal is 23894 square millimeters (156 single crystals do not have basically only a small chamfer angle)

The polycrystalline area is 24,336 square millimeters (156 polycrystalline have almost no chamfer)

The thickness is basically 200 um

Under sunlight, light energy is immediately converted into electrical energy. The DC energy it emits can be directly charged to mobile phones and calculators; electrical energy can also be stored in thea battery then reversed to 220 V AC power. The most commonly used are amorphous silicon, monocrystalline silicon and polycrystalline silicon, which are widely used. A 100W silicon battery covers an area of ​​about 100 square meters, has a lifespan of 20 years and a shelf life of 5 years.
