Conclusions We presented studies of n-type polySi passivating contacts and their application on the back side of a high-performance bifacial n-type solar cell with fire-through screen-printed metallization, processed on 6″ Cz wafers. The cell design is tentatively called PERPoly (Passivated Emitter Rear Polysilicon contact).
How efficient is a screen-printed bifacial n-type device?
To date, the highest cell efficiency reported for a fully screen-printed bifacial n -type device is 21.5%, utilizing ion-implantation for emitter and back surface field (BSF) formation – this value increases to 21.8% with the use of a triple-layer front antireflection coating (ARC) which utilizes a silicon oxide capping layer.
How are 239 cm 2 n-type solar cells produced?
239 cm 2 n-type solar cells were produced according to standard industrial process steps with the exception of replacing a diffused Back Surface Field (BSF) with n-type doped polySi/SiO x contacts, as shown in Fig. 1. After double sided LPCVD deposition the polySi/SiO x stack is chemically removed from the front.
