Title:
Perovskite–silicon tandem solar cells using zinc-doped tin oxide achieve comparable performance to indium tin oxide counterparts
Detail:
Fraunhofer ISE-led researchers demonstrated zinc-doped tin oxide (ZTO) as an indium-free alternative to indium tin oxide (ITO) for recombination layers in fully textured perovskite–silicon tandem solar cells. ZTO delivers comparable device efficiencies of 27–28% under current-matching conditions, offering a scalable, indium-free pathway for high-performance tandem photovoltaics without efficiency loss.
