Poly Crystalline Silicon Solar Cell

Poly solar cells of over 4 bus bars now have been a trend for high-power poly solar modules. Due to more and thinner bus bars filmed on the cell surface, poly cells are enpowered to have stronger capability to take in energy from the sunshine and enable it to reach efficiency up to 20% or above. It is believed that in the very near future, PV panel efficiency will reach the same level due to the innovation of assembly techniques and upgrading of other module material, including highly tranparent toughed solar glass, EVA, welding ribbon, and backsheet.
