Italian photovoltaics (PV) maker MegaCell Srl has reached 25% efficiency with its BiSoN bi-facial N-type monocrystalline cells in the production industrial process.
The company said earlier this week it has surpassed, on the production line, a cell efficiency of 21% on the front side, and a bifaciality factor of 90%. With the 20% back side contribution, the overall bifacial cell efficiency rises to 25%.
The new generation BiSoN cell has more than 5.17 W on the front side and uses 4 bus-bar technology. The BiSoN modules, which are made of 60 bi-facial cells, exceed 300 Wp on the front side and 270 Wp on the back one. Thus the overall module is rated at 375 Watt equivalent.
MegaCell noted that the glass-glass technology it uses ensures 50 years module life.
At a 2.5-MW PV plant in Chile, currently under construction, MegaEngineering is to demonstrate how bifacial solar can lower the cost of solar energy. MegaGroup estimates that in very sunny regions it is possible to bring the cost of solar power as low as USD 35 (EUR 32) to USD 40 per MWh.
