Area 2: Will we have >22%  Efficient Multi-Crystalline Silicon Solar Cells?

Multicrystalline Silicon technologies represents more than 65% of 2015 global shipments. Over the last two years, the best p-type multicrystalline silicon solar cells developed by Trina Solar have reached new efficiency records, up to 20.86% in 2014 and 21.25% in 2015. These achievements result from improvements of all aspects of the solar cell fabrication: contamination control, development of high-performance multi-crystalline silicon wafers, cell design and process optimization. Analysis show that efficiencies above 22% are possible with p-type multi-crystalline and could be reached in the next few years.
