摘要

由于后侧通风减少,光伏建筑一体化(BIPV)容易出现较高的工作温度,这可能会影响其长期性能和可靠性。然而,在研究光伏组件的热机械应力时,人们往往忽略了云层移动和随后的辐照度变化等因素导致的日内温度变化。这项研究对瑞士纳沙泰尔测试台上单电池晶体硅组件的电池和组件温度测量结果进行了统计分析。目的是研究和比较各种与 BIPV 相关的模块拓扑结构,以及绝缘类型、倾斜角度和玻璃厚度等一系列因素。研究考察了第 98 百分位数温度和昼夜温度变化等标准指标,以及基于温度梯度和电池与组件温差提出的新热机械应力指标。出乎意料的是,研究结果表明,考虑到日间温度变化,与暴露在较高工作温度下的全隔热组件相比,封闭式屋顶组件配置(通风间隙小)遭受长期热机械疲劳的潜在风险更高。

Towards a quantification of thermal and thermomechanical stress for modules in building-integrated photovoltaics configurations

Due to reduced rear-side ventilation, building-integrated photovoltaics (BIPV) are prone to higher operating temperatures, which may impact their long-term performance and reliability. However, often overlooked in the study of thermomechanical stress in PV modules are the intraday temperature variations, resulting from factors such as cloud movements and subsequent changes in irradiance. This work proposes a statistical analysis of cell and module temperature measurements in single-cell c-Si modules on a test bench in Neuchâtel, Switzerland. The goal is to study and compare various BIPV-relevant module topologies with a range of factors such as the insulation type, tilt angle, and glass thickness. The standard indicators such as the 98th percentile temperature and diurnal temperature variations are examined, as well as proposed new thermomechanical stress indicators based on temperature gradients and cell versus module temperature differences. Unexpectedly, results indicate that, considering the intraday temperature variations, close-roof module configurations (with small ventilation gaps) are potentially at a higher risk of suffering long-term thermomechanical fatigue than fully insulated modules, which are exposed to higher operating temperatures.

期刊介绍: Progress in Photovoltaics offers a prestigious forum for reporting advances in this rapidly developing technology, aiming to reach all interested professionals, researchers and energy policy-makers. The key criterion is that all papers submitted should report substantial “progress” in photovoltaics. Papers are encouraged that report substantial “progress” such as gains in independently certified solar cell efficiency, eligible for a new entry in the journal''s widely referenced Solar Cell Efficiency Tables. Examples of papers that will not be considered for publication are those that report development in materials without relation to data on cell performance, routine analysis, characterisation or modelling of cells or processing sequences, routine reports of system performance, improvements in electronic hardware design, or country programs, although invited papers may occasionally be solicited in these areas to capture accumulated “progress”.
