摘要

作为向去碳化电力部门过渡的一部分,太阳能光伏(PV)组件的部署在全球范围内激增。然而,由于长期暴露在室外条件下,未来的气候变化会带来组件降解问题。在此,我们确定了单晶硅(Mono-Si)组件的主要降解机制,并对其在各种气候情景下的降解模式进行了实证建模。由于热降解机制,组件的降解速度往往较快。我们估计,到 2059 年,加权平均降解率将增加到每年 0.1%。在评估组件退化对未来光伏发电和平准化能源成本的影响时,我们预计功率损耗将增加 8.5%,导致未来能源价格上涨约 10%。这些结果凸显了通过谨慎选择材料和改进组件制造工艺来设计不受气候影响的光伏组件的必要性。特别是,我们建议在组件中使用散热技术,以防止过热导致的性能下降。

Accelerated degradation of photovoltaic modules under a future warmer climate

Solar photovoltaic (PV) module deployment has surged globally as a part of the transition towards a decarbonized electricity sector. However, future climate change presents issues for module degradation due to prolonged exposure to outdoor conditions. Here, we identify key degradation mechanisms of monocrystalline-silicon (mono-Si) modules and empirically model their degradation modes under various climate scenarios. Modules tend to degrade faster due to the thermal degradation mechanism. We estimate that the weighted average degradation rate will increase up to 0.1%/year by 2059. On assessing the impacts of module degradation on future PV power generation and levelized cost of energy, we project up to 8.5% increase in power loss that leads to ~10% rise in future energy price. These results highlight the need to climate-proof PV module design through careful material selection and improvements in the module manufacturing process. In particular, we recommend the use of heat dissipation techniques in modules to prevent degradation due to overheating.

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”.
