January 21st, We were very pleased to welcome Pr. Henry Snaith to discuss possible collaboration opportunities on perovskite solar cell fabrication and characterization. Henry Snaith is professor at the university of Oxford and is working at the Clarendon Laboratory. He pioneered the field of perovskite based solar cells and his research activity leads to some of the greatest advances in this field. Among many other examples, one can mention: – the first fabrication of a

IPVF has just developed and patented a new solar cell architecture in III-V material by MBE growth (Molecular Beam Epitaxy). This new cell, made of AlGaAs and InGaP, achieved a conversion efficiency of 18.7% certified by the Franhofer ISE CalLab. This efficiency exceeds the previous MBE world record of 16.6%. This cell, with a bandwidth of 1.73eV, is particularly well suited to future tandem silicon-based cells under development at IPVF. Several development options have already
