Researchers in China found that fine tuning the lead(II) oxide (PbO) and silicon dioxide (SiO₂) molar ratio in silver paste glass frits affects silver-silicon contact resistance in crystalline silicon solar cells. They found that an intermediate ratio optimizes interfacial structure, lowering contact resistance and improving efficiency by 1 percentage point…
