Researchers at the German research institute have demonstrated that the so-called EpiWafers could be used directly for solar ...

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

Structure of a TOPCon solar cell. Image Credit: KLA Instruments ™ Figure 4 shows ... After cleaning the residue, a thin oxide (SiO x) tunnel layer is thermally grown on the rear surface, followed by a ...

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 ...

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%.

In solar panel making, silver paste gets laid down careful-like. It's screen-printed onto the silicon wafer—shapes tiny grid lines that act as juice contacts. After that, the wafer hits a hot firing ...

New research has shown how improving top-cell transparency and performance remains key to the commercialization of tandem perovskite-silicon solar ... a tunnel junction. This design is ideal for ...
