Description：
The average conversion efficiency of monocrystal silicon solar cells could be more than 16% , and the maximum could achieve to 24%. This is the highest efficiency of converting from light to electricity among all the solar cells. But the cost of it is so high that it isn’t been used widely . The monocrystal silicon adopts toughened glass and impermeable resin for encapsulation , It is strong ,with using life 15 years or even more than 25 years.
