New world record efficiency for large area metal wrap through silicon heterojunction solar cells

Japanese solar-PV manufacturer Choshu and Dutch energy research institute ECN have achieved a world record solar cell efficiency of 23.1% with combined silicon heterojunction and metal wrap though solar cells. The results have been obtained on large area commercial n-type silicon wafer. This architecture combines the best of the two technologies and improves module power, reduces cost and provides aesthetically appealing PV modules. Results will be presented at IEEE PVSC and EU-PVSEC conferences this month in US and Germany.
