Abstract

A theoretical model is proposed for a concentrator photovoltaic (CPV) system. This model is based on the two-diode equation and considers the luminescent coupling (LC) effect in III-V triple junction solar cell. By using the model, the ‘I-V’ curve of the system is fitted. The fitting result is in good agreement with the experimental data. The system’s open circuit voltage is also predicted in a certain temperature range. Based on the analysis of the simulation results and the two-diode equation, it is concluded that the LC effect should be a non-negligible mechanism for analyzing the operation performance of CPV system.

III-V三结太阳能电池聚光光伏系统建模中的发光耦合效应研究

摘要

提出了一种聚光光伏（CPV）系统的理论模型。该模型基于双二极管方程，并考虑了 III-V 三结太阳能电池中的发光耦合 (LC) 效应。通过使用该模型，拟合了系统的“I-V”曲线。拟合结果与实验数据吻合较好。系统的开路电压也在一定的温度范围内进行了预测。通过对仿真结果和双二极管方程的分析，得出结论，LC效应应该是分析CPV系统运行性能不可忽略的机制。
