In organic photovoltaic (OPV) systems, exciton dissociation and ultrafast charge separation at donor-acceptor heterojunctions both play a key role in controlling the efficiency of the conversion of excitation energy into free charge carriers. In this work, nonadiabatic dynamics simulations based on the quantum-classical Liouville equation are employed to study the real-time dynamics of exciton dissociation and charge separation at a model donor-acceptor interface.

Vibration-mediated resonant charge separation across the donor-acceptor interface in an organic photovoltaic device.

A concise dissipative two-level electronic system coupled to a molecular vibrational mode is proposed and solved quantum mechanically, and it is found that the charge transfer is enhanced substantially when the vibrational energy quanta is equal to the electronic energy loss across the interface.

Even a little delocalization produces large kinetic enhancements of charge-separation efficiency in organic photovoltaics

In organic photovoltaics, charges can separate efficiently even if their Coulomb attraction is an order of magnitude greater than the available thermal energy. Delocalization has been suggested to

Benchmarking the forward-backward trajectory solution of the quantum-classical Liouville equation.

The analysis of the accuracy of the forward-backward trajectory solution (FBTS) of the quantum-classical Liouville equation is presented and it is concluded that the FBTS is considerably more accurate than the PBME and the perturbative approaches for most realistic parameter sets and is, therefore, more versatile.

Low-Dimensional Semiconductors in Artificial Photosynthesis: An Outlook for the Interactions between Particles/Quasiparticles

This Outlook reviews recent advances in studying the unique interactions in low-dimensional semiconductor-based photocatalysts and describes the impacts of the interactions on photosynthetic energy conversion.

A partially linearized spin-mapping approach for nonadiabatic dynamics. II. Analysis and comparison with related approaches.

A thorough comparison of the terms in the underlying expressions for the real-time quantum correlation functions for spin-PLDM and fully linearized spin mapping is presented in order to ascertain the relative accuracy of the two methods.

A partially linearized spin-mapping approach for nonadiabatic dynamics. I. Derivation of the theory.

The spin partially linearized density matrix approach, which uses the Stratonovich-Weyl transform to describe the electronic dynamics for each path within the spin-mapping space, appears to give the method superior accuracy for computing dynamical observables of interest when compared with other methods within the same class.

Hot charge-transfer excitons set the time limit for charge separation at donor/acceptor interfaces in organic photovoltaics.

This real-time view of hot CT exciton formation and relaxation using femtosecond nonlinear optical spectroscopies and non-adiabatic mixed quantum mechanics/molecular mechanics simulations in the phthalocyanine-fullerene model OPV system sets the fundamental time limit for competitive charge separation channels that lead to efficient photocurrent generation.

Non-Markovian Quantum-Classical Ratchet for Ultrafast Long-Range Electron-Hole Separation in Condensed Phases.

It is demonstrated that the non-Markovian effect originating from the slow polaron formation strongly suppresses the electron-transfer reaction back to the interfacial charge-transfer state stabilized at the donor-accepter interface and that it plays a critical role in maintaining the long-range electron-hole separation.

This paper discusses the mechanism of generation of free charges in organic photovoltaic cells (OPV) from electrostatically bound electron–hole pairs. The efficiency of this process is explained when

The Role of Driving Energy and Delocalized States for Charge Separation in Organic Semiconductors

Atomic modeling showed that the IR photons promote bound charge pairs to delocalized band states, similar to those formed just after singlet exciton dissociation, which indicates that such states act as the gateway for charge separation.

Understanding the free energy barrier and multiple timescale dynamics of charge separation in organic photovoltaic cells.

It is found that the combined effects of the external electric field, entropy, and charge delocalization reduce the free energy barrier significantly and only a small energy offset between the band gap and the lowest energy CT state is needed to achieve efficient free charge generation in OPV devices, which agrees with recent experimental findings.

Concurrent Effects of Delocalization and Internal Conversion Tune Charge Separation at Regioregular Polythiophene-Fullerene Heterojunctions.

This work addresses a model donor-acceptor junction representative of regioregular P3HT-PCBM, using high-dimensional quantum dynamics simulations by multiconfigurational methods and finds a delocalized initial bright state proves less prone to electron-hole capture by the interfacial trap than a localized, vibronic wavepacket close to the interface.

Ultrafast charge separation in organic photovoltaics enhanced by charge delocalization and vibronically hot exciton dissociation.

Calculations show that experimentally observed efficient charge separations can be explained by a combination of two effects: first, the delocalization of charges which substantially reduces the Coulomb barrier, and second, the vibronically hot nature of the charge-transfer state which promotes charge dissociation beyond the barrier.

A minimal model of the donor-acceptor interface encountered in organic solar cells is introduced and the process of charge separation is mostly a purely electronic process and a very similar physics can be described neglecting the role of nuclear degrees of freedom altogether.
