论文摘要
在第三代光伏设备中，光电转换效率提高的主要物理机制是单线裂变（SF）。为了准确描述SF并在理论上揭示物理过程，我们基于先前模型引入了SF动力学中的异常过程（AP），包括异常裂变，异常融合，异常分离和三胞胎对状态的异常分离和组合的组合，单个三胞胎激子的扩散。动力学模型以时间依赖性系数研究了AP对SF的影响。此外，根据结果，我们为实验数据提供了最佳模拟[G。 B. Piland等人，J。Phys。化学C，2013，117，1224]通过调整修改动力学方程中的速率系数和指数。结果表明，所考虑的AP比以前更准确地描述了SF动力学，表明AP确实存在于SF中。该模型还为如何改变实验性的物理因素来使SF发生趋向于需要方向，为理论基础提供了理论基础。
In the third generation photovoltaic device, the main physical mechanism that the photoelectric conversion efficiency is enhanced is the singlet fission (SF). In order to accurately describe the SF and reveal physical process in theoretically, we introduce the anomalous process (AP) in SF dynamics based on previous model, including anomalous fission, anomalous fusion, anomalous dissociation and combination of triplet pair states, anomalous decay and diffusion of single triplet exciton. The effects of the AP on SF are investigated by the kinetic model with time-dependent coefficient. Further, according to the results we make the optimal simulations for the experimental data [G. B. Piland et al., J. Phys. Chem. C, 2013, 117, 1224] by adjusting the rate coefficients and exponents in the mended kinetic equations. The results show that the model considered AP is more accurate than previous that to describe SF dynamics, demonstrating that the AP do exist in SF. The model also provides the theoretical foundation for how varies experimentally physical factors to make SF occur to tend to required direction.
