The company says that this is the highest efficiency verified for a 156×156 mm multicrystalline silicon PV cell, and follows on its progress in high-crystal quality, low dislocation density multi-Si casing and wafering. JA Solar plans to integrate the new technology into existing manufacturing lines.

“This latest advance is a real testament to the exceptional R&D work going on at JA Solar, and another key step in our efforts to meet the growing demand for high-performance solar power products,” said JA Solar Chief Technology Officer Yong Liu.

“The superior conversion efficiency we’ve achieved with our multi-Si cells and the rest of our product offering creates significant value for customers as it increases power generated per square foot and lowers installation cost per watt.”
