    • The term exciplex was originally employed in photochemical studies to refer the formation of an excited state molecular complex, observed in systems where optical excitation of monomeric molecular species was observed to result in the formation of molecular dimers see ref 34, As such, the use of this term for solid-state molecular systems where optical excitation does not result in a significant change in donor-acceptor spatial separation is rather questionable

    • The Coulombic binding of the initially formed BRPs can be estimated to be 410 meV, assuming a relative dielectric constant of 3.5 (an average value for P3HT, ε = 3 (ref 70), and PCBM, ε = 4.1 (ref 71)) and spatial separation of 1 nm. Larger spatial separations of 2 or 3 nm would give binding energies of ∼210 and 140 meV, respectively.
