Via a tube-type industrial plasma-assisted atomic layer deposition (PEALD ... research team has fabricated a tunnel oxide passivated contacts (TOPCon) solar cell through a new technique enabling ...

An international research team has developed a metallization technique for TOPCon solar cells that can reportedly reduce ...

Image: Bert Thin Films. Kentucky-based Bert Thin Films has used a proprietary copper paste on a tunnel oxide passivated contact (TOPCon) M10 solar PV cell with a conversion efficiency of 24%.

On the rear side, the TOPCon solar cell uses a SiO x /n-poly silicon passivation layer, which favors one type of carrier to tunnel and blocks the other one. This passivation layer reduces the ...
