Paper Abstract

In this work, we first proposed a comprehensive numerical simulation for luminescent coupling efficiency (LCE) in a complete multi-junction (MJ) configuration and discussed its dependencies on temperature, incident light spectrum and bias voltage. We used finite difference time domain (FDTD) method and detailed balance principle to establish an optical transfer model. Based on that, we revealed the predominant influence factors of the simulation results in detail. This work will certainly fill a knowledge gap in understanding LCE and provide guidance to MJ photovoltaic device design and optimization as well.
