Vraag: Wat is HJT -module?
A: Heterojunction (HJT) is een speciale PN-junctie, die twee verschillende technologieën in één cel combineert: een kristallijne siliciumcel ingeklemd tussen twee lagen amorf "dun-film" silicium. In vergelijking met het gebruik van elke technologie alleen, kunnen deze technologieën samen worden gebruikt om meer energie te oogsten.
Vraag: Wat is N -type zonnecel ?
A: Een N-type zonnecel bestaat uit een dun p-type silicium (gedoteerd met boor) laag over een veel dikker N-type silicium (gedoteerd met fosfor) laag. Elektrische contacten worden op beide zijden toegepast. De P-kant is de voorkant naar de zon.
