双面PV农场的温度依赖能量增益：全球视角
Temperature Dependent Energy Gain of Bifacial PV Farms: A Global Perspective
摘要：
双面太阳能电池板被认为是下一代太阳能发电场的首选技术，因为它们以略微增加的成本增加了能源产量。随着双面农场在世界各地的激增，重要的是要研究双面太阳能农场相对于单面农场，独立双面模块和各种竞争性双面技术的温度依赖性能量产量和平准化能源成本（LCOE）的作用。在这项工作中，我们将辐照度和光收集模型与实验验证的基于物理的温度依赖性效率模型相结合，以比较世界各地各种双面技术的能量产量和LCOE减少。我们发现，温度相关的效率改变能量产量和LCOE约-10至15%。事实上，结果会因农场的位置（定义照明和环境温度）、模块的高度（增加入射能量）以及各种双面技术的温度系数而显著不同。本文中提出的分析将使我们能够现实地评估下一代双面太阳能发电场的特定位置的相对优势和经济可行性。
英文摘要：
Bifacial solar panels are perceived to be the technology of choice for next generation solar farms for their increased energy yield at marginally increased cost. As the bifacial farms proliferate around the world, it is important to investigate the role of temperature-dependent energy-yield and levelized cost of energy (LCOE) of bifacial solar farms relative to monofacial farms, stand-alone bifacial modules, and various competing bifacial technologies. In this work, we integrate irradiance and light collection models with experimentally validated, physics-based temperature-dependent efficiency models to compare the energy yield and LCOE reduction of various bifacial technologies across the world. We find that temperature-dependent efficiency changes the energy yield and LCOE by approximately -10 to 15%. Indeed, the results differ significantly depending on the location of the farm (which defines the illumination and ambient temperature), elevation of the module (increases incident energy), as well as the temperature-coefficients of various bifacial technologies. The analysis presented in this paper will allow us to realistically assess location-specific relative advantage and economic viability of the next generation bifacial solar farms.
