In this work, we assess the possible reasons for the differences observed in open circuit voltage (VOC) in mixed cation perovskite solar cells when comparing four different hole transport materials (HTMs), namely TAE-1, TAE-3, TAE-4 and spiro-OMeTAD. All these HTMs present close chem. and phys. properties, however, once they are finally deposited onto the perovskite layer, the HTMs provide different performance characteristics. Addnl. to the evaluation of the HTM influence on recombination, we find that, upon deposition of the organic HTM on top of the perovskite, there is an important change in the energy level position, and the impact on the device VOC is discussed. We consider that this exptl. observation could be general for other organic HTMs and would justify the difficulties in finding mols. and materials that could improve the efficiency of perovskite solar cells overcoming the solar-to-energy conversion efficiency of solar cells made using spiro-OMeTAD as a hole selective contact. In the experimental materials used by the author, we found Bis(4-methoxyphenyl)amine(cas: 101-70-2Product Details of 101-70-2)
Bis(4-methoxyphenyl)amine(cas: 101-70-2) is a diphenylamine derivative used as a chemical additive for cured rubber.Bis(4-methoxyphenyl)amine is highly toxic and may potentially induce chromosome abberation.Product Details of 101-70-2
