We are back!
Our Perovskite/Silicon Tandem Solar Cells entered the @NREL chart with a certified efficiency of 32.5%

Thanks to all the amazing people contributing to this achievement.

@HZBde was well represented at #TandemPV22 presenting newest developments on perovskite/silicon tandem solar cells.

What a great venue in the Stadium of @scfreiburg!
Thank you @FraunhoferISE and @StefanGlunz

In collaboration with Q CELLS we have shown that industrial, cost-efficient silicon solar cells are viable for tandems with 28.7% efficiency.

Congrats to Kári Sveinbjörnsson @SveKari and Bor Li for their diligent processing! @HZBde #HySPRINT
