A focus on improving the module's optical gains and reducing cell-to-module resistance losses as well increasing the cell area by reducing interconnect shadowing were behind the conversion efficiency gains. 

JinkoSolar had only recently set a new record conversion efficiency of 24.90% for its N-type TOPCon monocrystalline silicon solar cell, independently verified by the Institute for Solar Energy Research in Hamelin (ISFH), Germany.

The company had set a previous module power record of 387.6W for an N-type TOPcon half-cell module (60P) in January 2019. 

JinkoSolar had 800MW of N-type TOPCon module assembly capacity in 2020.
