Non-fullerene acceptor (NFA) materials have posed new paradigms for the design of organic solar cells (OSC), whereby efficient carrier generation is obtained with small driving forces, in order to maximize the open-circuit voltage (VOC). In this paper we use a coarsegrained mixed quantum-classical method, that combines Ehrenfest and Redfield theories, to shed light on charge generation process in small energy offset interfaces. We have investigated the influence of the energetic driving force…

Anatomy of the energetic driving force for charge generation in organic solar cells
Nakano et al. suggest that the dominant driving force is the energy difference between the singlet excited state and the charge transfer state after assessing 16 material combinations.
Barrierless Free Charge Generation in the High-Performance PM6:Y6 Bulk Heterojunction Non-Fullerene Solar Cell.
Free charge generation in the high-performance blend of the donor polymer PM6 with the NFA Y6 is thoroughly investigated and it is shown that photocurrent generation is essentially barrierless with near-unity efficiency, regardless of excitation energy.
Charge Generation in Organic Solar Cells: Interplay of Quantum Dynamics, Decoherence, and Recombination
The dynamics of photoinduced charge generation is studied for donor–acceptor (D–A) organic interfaces, with focus on the interplay of quantum dynamics, decoherence effects, and recombination. A
A unified description of non-radiative voltage losses in organic solar cells
Recent advances in organic solar cells based on non-fullerene acceptors (NFAs) come with reduced non-radiative voltage losses (ΔVnr). Here we show that, in contrast to the energy-gap-law dependence
Charge Dynamics in Organic Photovoltaic Materials: Interplay between Quantum Diffusion and Quantum Relaxation
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
Hot exciton dissociation in polymer solar cells.
This work directly targets the interfacial physics of an efficient low-bandgap polymer/PC(60)BM system and rationalizes these findings in terms of a higher degree of delocalization of the hot CTSs with respect to the relaxed ones, which enhances the probability of charge dissociation in the first 200 fs.
Assessing the nature of the charge-transfer electronic states in organic solar cells
Chen et al. develop a three-state vibronic model that allows them to provide a reliable description of the optical absorption features related to the charge-transfer states and to underline the erroneous interpretations stemming from the application of the semi-classical two-state model.
Coherent ultrafast charge transfer in an organic photovoltaic blend
The results show that coherent vibronic coupling between electronic and nuclear degrees of freedom is of key importance in triggering charge delocalization and transfer in a noncovalently bound reference system.
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.
Molecular understanding of organic solar cells: The challenges
A key feature of π-conjugated organic semiconductors that has impacted the design and geometry of organic photovoltaic devices for the past decades is the excitonic character of their optical
