Incoherent hopping
WebJan 29, 2016 · At room temperature, the charge carriers in organic single crystals are localized and the charges transport in a sequential hopping mode between neighboring molecules which could be described by the incoherent hopping mechanism. 16 Using the hopping mechanism, the charge transfer rate between neighboring molecules, k, can be … Crystalline solids and molecular solids are two opposite extreme cases of materials that exhibit substantially different transport mechanisms. While in atomic solids transport is intra-molecular, also known as band transport, in molecular solids the transport is inter-molecular, also known as hopping transport. The two different mechanisms result in different charge mobilities. In disordered solids, disordered potentials result in weak localization effects (traps), which reduc…

WebMar 16, 2024 · The presented free-energy description of energy transfer reveals that typical photosynthetic systems operate in an almost barrierless regime. The approach also provides insights into the distinction between coherent and incoherent energy transfer and the criteria by which the necessity of the vibrational assistance is considered. WebMay 4, 2024 · We demonstrate that efficient and nearly field-independent charge separation of electron-hole pairs in organic planar heterojunction solar cells can be described by an incoherent hopping mechanism. Using kinetic Monte Carlo simulations that include the effect of on-chain delocalization as well as entropic contributions, we simulate the ...
WebHopping is an incoherent, thermally activated process in which an electron moves from one site to another but loses all information about its phase in the process. In other words, there is no coherence between the amplitudes for finding an electron at different lattice sites.
