Cu(TFSI)2-Doped Hole Conductors for Efficient CH3NH3PbI3 Perovskite Solar Cells

Mukundan Thelakkat

One of the challenges in n-i-p perovskite solar cells is to create stable doped (n and p) extraction layers. In this paper (ACS Applied Energy Materials 2019, ASAP) we demonstrate the use of

Cu(TFSI)2 as dopant for spiro-OMeTAD without the need of additives such Li-TFSI or tBP and air-doping
