Solar PV Passivation, Photovoltaic rear surface passivation. Current PV solar cell market is struggling to bring economy trade off. Since the economy is the product of cost to performance, and costs are standardized, only factor remains is to increase efficiency and performance of solar cell.
The chemicals are available in liquid form. The in-line automated multitank system is recommended. It contributes reduction in Recombination Velocity of electrons.
This is very new and innovative products. Products may turn disruptive technology in upcoming days.
Role of Passivation
The surface recombination at the rear surface affects efficiency of solar cell. To reduce surface recombination the passivation of rear surface is done. We deliver the passivation chemicals to the rear surface of the crystlline silicon solar cell. This brings surface recombination velocity SRV to lowest possible. With this, output from solar cell is enhanced.
