Electrochemical Determination of the Ionization Energy and the Electron Affinity of Lead Halide Perovskite Thin Films: A Comparison to Ultraviolet Photoelectron Spectroscopy

Reliable determination of ionization energies (IE) and electron affinities (EA) is essential for understanding energy‐level alignment in solar cells. Here, we benchmark cyclic voltammetry (CV) and electrochemical voltage spectroscopy (EVS) for IE and EA determination against ultr...
