Sensitivity of photovoltaic cells efficiency to initial conditions in various aggregation designs

Year: 2024

Type: article

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 .
