Abstract

Operating in wet conditions The high efficiency of the complex organic molecule Spiro-OMeTAD as a hole-transporting material for perovskite solar cells requires the use of hygroscopic dopants that decrease stability. Jeong et al. synthesized hydrophobic fluorinated analogs of Spiro-OMeTAD as hole-tr...
