Fully Conjugated Co‐Self‐Assembled Monolayers for Efficient and Stable Inverted Perovskite Solar Cells

, efficient charge transport, and minimize buried interfacial defects. Accordingly, the CzTPA modification can significantly enhance the efficiency of 1.54-eV PSCs from 23.53% to 25.66% and sustain 91.4% of its original efficiency after 1992 h under continuous illumination at 65 °C. More importantly, a 1.68 eV of wide-bandgap PSC achieved a PCE of 22.75% with good photostability.
