Abstract

Curved surfaces look smart for automotive customers, however, are not easily accommodated by conventional flat photovoltaic (PV) panel technology. One of the major challenges for curved PV technology is to develop a consensus method for measuring the current–voltage characteristics of curved PV modules. In this study, we first investigated the current–voltage characteristics of a flexible crystalline silicon (c-Si) solar cell on a curved stage and modeled the effect of the solar cell curvature on the current characteristic. Then, we characterized the irradiance distribution of a solar simulator for a large PV module with an illumination area of 200 × 140 cm², including spatial light intensity and incident light angle distributions. Based on these results, we demonstrated that the measured current–voltage curve of a curved c-Si PV module with a size of ∼120 × 70 cm² and a curvature radius of 1000 mm matched the calculated current–voltage curves considering the irradiation characteristics of the solar simulator and the current–voltage curve of a flat PV module. The requirements for the solar simulator used to measure the current–voltage characteristics of a curved PV module are discussed.

车载一体化弯曲光伏组件的电流电压特性测量

对于汽车客户来说，曲面看起来很漂亮，然而，传统的平面光伏（PV）面板技术不容易适应。弯曲光伏技术面临的主要挑战之一是开发一种一致的方法来测量弯曲光伏组件的电流电压特性。在这项研究中，我们首先研究了柔性晶体硅（c-Si）太阳能电池在弯曲台上的电流-电压特性，并模拟了太阳能电池曲率对电流特性的影响。然后，我们对200 × 140 cm2照明面积的大型光伏组件太阳模拟器的辐照度分布进行了表征，包括空间光强和入射光角分布。基于这些结果，我们证明了考虑太阳模拟器的辐照特性和平板光伏组件的电流电压曲线，尺寸为~ 120 × 70 cm2，曲率半径为1000 mm的弯曲c-Si光伏组件的实测电流电压曲线与计算的电流电压曲线相匹配。讨论了用于测量弯曲光伏组件电流电压特性的太阳模拟器的要求。
