Principles of Solar Cell using
Production
How is the solar cell produced?
The production is divided to two parts. 1, Solar Panel Production 2, The Production of Solar Cells
THANK YOU!
Let us achieve the each building turned into a small power station and the good work!
Principle
The basis is the Photovoltaic effect
• hv> Eg；
• Because of Vbi , it will induce photon current ；
• Voltage is formed (across the pn junction)。
monocrystalline silicon conversion efficiency of typically 10% -15%, while the conversion efficiency of polycrystalline silicon 12% -16%.

Power in the remote area
➢ Solar cells can be used as power in the remote area, mountain district, desert, and island and so on, so it can significantly reduce the costs for no longdistance transmission
