论文摘要
分子光细胞，即单个分子供体 - 受体复合物，除了技术上很重要之外，它是在强非平衡中运行的多体系统的范式示例。通过求解lindblad主方程，在开放量子系统方法中研究了光电器的量子传输和光电的光伏能转换效率。对应于分子（通过电子 - phonon相互作用）和环境（通过dephasing）对应于分子的振动振动程度的相互作用显示其在最大功率下的效率中的签名。当系统不遭受驱动时，我们发现培养基在培养基中的振动辅助电子传输，从而在培养基中，从而在强烈的电子偶联方向上进行振动。暴露于Dephasing Hampers，这种振动有助于电子传输，在特定的除多速率范围内。
The molecular photo cell, i.e., a single molecule donor-acceptor complex, beside being technologically important, is a paradigmatic example of a many-body system operating in strong non-equilibrium. The quantum transport and the photo-voltaic energy conversion efficiency of the photocell, attached to two external leads, are investigated within the open quantum system approach by solving the Lindblad master equation. The interplay of the vibrational degrees of freedom corresponding to the molecules (via the electron-phonon interaction) and the environment (via dephasing) shows its signature in the efficiency at maximum power. We find vibration assisted electron transport in the medium to strong electron-phonon coupling regime when the system does not suffer dephasing. Exposure to dephasing hampers such a vibration assisted electron transport in a specific range of dephasing rate.
