This study, which came out in the recent issue of ACS Applied Materials & Interfaces, successfully demonstrates the Lewis-acid (TPFB) doping of the widely used spiro-OMeTAD hole transport materials for perovskite solar cells to. This dopant replaces the conventional LiTFSI/tBP doping. By doing so, the device stability is increased and processing is simplified.
