PERC Technology in Solar Modules explained
, Published On: December 11, 2018
The solar PV Module industry has been dominated by one primary solar cell and module technology for more many years now – Aluminum Back Surface Field (“Al-BSF”). However, this technology is near its practical limit and further gains in efficiency are unlikely. The search for continued efficiency improvements has led the industry to adopt Passivated Emitter and Rear Contact (“PERC”) solar cells. PERC cells enabled access to module with higher power ratings of up to 370 W for a 72-cell module and power ratings could cross 400 Wp in the near future. Undoubtedly, there has been a lot of excitement…
