4BB-Design reduces cell series resistance and stress between cell connection lines and improves the reliability and efficiency of the modules

Average mass production conversion efficiency > 18.8%

RIECIUM High Efficiency Multi Cell

Fine double-printing

Excellent anti-PID performance

JA Solar started mass production of PID-resistant cells (under the following conditions: 60°C, 85% humidity, -1000V, 96 hours) in October 2012.

Lower power loss through encapsulation

Appropriate electrical performance parameters (high voltage and low voltage)
Current evaluation and positive tolerance for the cell performance compensation guarantee a very low loss from cells to modules.

Excellent solderability

Application of double-printing technology in production improves solderability.
