摘要

基于国际电工委员会(IEC)国际标准分析了引起标准太阳电池量值传递误差的因素及其与国际标准的一致性。随机选取我国市场上销售的6种封装标准太阳电池

测量了它们的温度特性、光谱响应特性和表面反射特性。结果表明:电池的封装结构影响它们的冷却效果及温度的正确测量

从而导致温度和短路电流的不稳定性

其变异系数最高可达0.12%和0.04%。另外

有、无偏置光条件下的光谱响应特性均反映其光电流的光照强度线性特性

这里定义用光谱拟合度来衡量各封装太阳电池的光谱响应特性。采用改变入射角测量短路电流的方法分析了表面光反射对短路电流的影响

利用余弦函数拟合确定了由表面反射光所引起的短路电流的误差可达0.21%。本文的研究成果对光伏行业正确制造、选择和使用标准太阳电池具有指导作用。

Abstract

This paper focuses on analysis of the origins of measuring transfer errors of standard solar cells and the uncertainty to international photovoltaic standards from the International Electrotechnical Commission(IEC). Six kinds of commercial packaged PV devices were chosen randomly

and their properties including temperature responsibility

spectral response and surface reflection effect were measured and evaluated based on the IEC standards

The results demonstrate that the structure of packaged PV device affects its cooling effect and temperature measurement accuracy

so that to leads to the instability of temperature and short-circuit current(I

). The variation coefficients are 0.12% for the temperature and 0.04% for the I

. Moreover

the spectral responses with and without white bias lights all reflect the linearity feature of incident light intensity for the I

in which the spectral responses were quantified by defining a spectral mismatch factor. The influence of surface reflection on I

was analyzed by measuring I

at different incident angles

and the ΔI

caused by the surface reflection was deduced to be up to 0.21% by fitting with a cosine function. The results provide the important guidance for the manufacture

selection and application of the packaged PV devices in photovoltaic industry.
