Abstract

It is thought that nature already exploits quantum mechanical properties to increase the efficiency of solar energy harvesting devices. Thus, 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.

各种聚合设计中光伏电池效率对初始条件的敏感性

人们认为，自然界已经利用量子力学特性提高了太阳能收集装置的效率。因此，可以通过巧妙设计纳米量子力学系统来提高这些设备的运行效率，其中量子相干性在这一过程中起着至关重要的作用。在这项研究中，我们建立了一个供体-受体两级陷阱偶极子模型，该模型融合了量子相干性的关键作用和聚集效应以及不同的初始状态。我们的分析表明，在最佳空间聚集效应的作用下，通过在特定初始状态下制备系统，可以实现淬灭不需要的发射。有趣的是，我们观察到，与经典同类产品相比，聚集诱导特性和带隙工程的量子效应可使功率增强高达 35.87%。这一令人鼓舞的趋势表明，仿自然光电设备的新型设计方面大有可为。

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
