Abstract Parity breaking at a centrosymmetric site, resulting in the appearance of an inversion electric dipole moment, is shown to enhance the polarizability and thus add an additional binding energy for the pairing of vibronic excitons into biexcitons. Implications of such formation of biexcitons in polarizable media like alkali halides are discussed. The possibility of electron-hole binding in layered perovskites, where the electron and hole move in the neighboring conducting planes, while binding is mediated by a highly polarizable partner in the intercalated insulating layer, is also considered.
