WebSep 16, 2024 · The electron affinity ( EA) of an element is the energy change that occurs when an electron is added to a gaseous atom to give an anion. In general, elements with the most negative electron affinities (the highest affinity for an added electron) are those with the smallest size and highest ionization energies and are located in the upper right ... WebElectron affinity is the energy change that results from adding an electron to a gaseous atom. For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol.Because this value is negative (energy is released), we say that the electron affinity of fluorine is favorable.

WebTherefore, the electron affinity of TiO 2 was set in the range of 4.1–4.5 eV in this study, and the simulation results are shown in Figure 4. It can be seen from Figure 4a that, with a gradual increase in the electron affinity of TiO 2, V oc shows a gradual downward trend, but the short-circuit current density (J sc) changes slightly.
