Abstract

This study introduces a novel methodology for the accurate characterization of photovoltaic (PV) devices that are using spectral distributions from various unfiltered light sources, including ASTM G173-03 solar irradiance, xenon arc lamp, metal halide lamp and tungsten halogen lamp within the 300–1300 nm wavelength range. By leveraging experimental values of external quantum efficiencies and open circuit voltages from nine distinct solar cell technologies, the authors calculated efficiencies with minimal deviation from the experimental benchmarks. The approach uniformly applies across all light sources, revealing a significant correlation between the power and spectrum of light sources that mitigates their spectral influence on solar cell output parameters. This work not only advances the understanding of light source effects on PV device performance but also proposes a correction methodology that significantly reduces evaluation errors, providing a pathway towards more accurate and cost-effective PV device testing and characterization.

使用未经过滤的光源时尽量减少光伏特性分析中的误差

摘要本研究介绍了一种新方法，用于准确表征光伏 (PV) 设备，该设备使用各种未过滤光源的光谱分布，包括 300-1300 纳米波长范围内的 ASTM G173-03 太阳辐照度、氙弧灯、金属卤化物灯和卤钨灯。通过利用九种不同太阳能电池技术的外部量子效率和开路电压的实验值，作者计算出的效率与实验基准的偏差最小。该方法统一适用于所有光源，揭示了光源功率和光谱之间的显著相关性，减轻了光源光谱对太阳能电池输出参数的影响。这项工作不仅加深了人们对光源对光伏设备性能影响的理解，还提出了一种可显著减少评估误差的校正方法，为实现更准确、更经济的光伏设备测试和表征提供了途径。
