摘要：
人们认为自然界已经利用量子力学特性来提高太阳能收集设备的效率。因此，通过巧妙设计纳米尺度的量子力学系统可以增强这些设备的运行，其中量子相干性在这一过程中起着关键作用。在本研究中，我们建立了一个供体-受体两能级陷阱偶极子模型，该模型融合了量子相干性和聚集效应的关键作用以及不同的初始状态。我们的分析表明，通过在最优空间聚集效应下将系统制备在特定初始状态，可以实现对不需要的发射的猝灭。有趣的是，观察到表征聚集诱导特性和带隙工程的量子效应可以将功率增强相比于经典对应物提高高达35.87%。这一令人鼓舞的趋势为模拟自然的光伏设备提出了一种有前景的新型设计思路。
英文摘要：
It is thought that nature already exploits quantum mechanical properties to increase the efficiency of solar energy harvesting devices. So, the operation of these devices can be enhanced by clever design of a nanoscopic, quantum mechanical system where the quantum coherence plays a crucial role in this process. In this investigation, we develop a donor-acceptor two-level trap dipole model converging the key role of quantum coherence and aggregation effects along with different initial states. Our analysis reveals that quenching unwanted emissions is achievable by preparing the system in specific initial state under the effect of optimal spatial aggregation. Interestingly it is observed that characterizing aggregation-induced properties and quantum effects of bandgap engineering can increase the power enhancement up to 35.87% compared with classical counterparts. This encouraging trend suggests a promising novel design aspect of nature-mimicking photovoltaic devices.
