This involves compacting PV glass with cells and a composite material using a binder, encasing the assembly in an aluminum alloy, and installing a junction box on the back. These multi-Si modules are essential for converting solar energy into electricity and are used in both residential and commercial solar panel installations. 本工业过程描述的是为光伏系统组装多晶硅（multi-Si）模块。这涉及使用粘结剂将PV玻璃与电池和复合材料紧凑地结合在一起，用铝合金外壳封装，并在背面安装接线盒。这些多晶硅模块是将太阳能转换为电能的关键部件，用于住宅和商业太阳能板安装。 GSvEbT284otn6Uxk366cUzLpnKe.png Unit process, single operation Attributional None 无 Allocation The goal of this study was to quantitatively assess the life-cycleenvironmental impacts of PV systems in China and provide a scientific basis for policy-making regarding the sustainable development of Chinese PV industry. 本研究旨在定量评估中国光伏系统的生命周期对环境的影响，为中国光伏产业的可持续发展政策制定提供科学依据。 None 无 None 无 The inventory data, including the material consumption andenvironmental emissions involved in the production of solar-gradesilicon, wafers, ingots, cells, and modules, were mainly collectedfrom companies that represent the current domain multi-Si PVtechnologies in China.

Life-cycle assessment of multi-crystalline photovoltaic (PV) systems in China. Journal of Cleaner Production 86, 180–190 (2015). Fu, Y., Liu, X. & Yuan, Z. Life-cycle assessment of multi-crystalline photovoltaic (PV) systems in China. Journal of Cleaner Production 86, 180–190 (2015). When utilizing the life-cycle assessment data for multi-Si PV modules in China, it is essential to integrate the material consumption and environmental emissions as outlined in this inventory data for the complete production process, from silicon to the final module assembly. Additionally, users should consider the energy consumption benchmarks from the 'Clean Production of Solar PV in China' report. The data set is optimized for assessing the environmental impacts in the Chinese context and should be used accordingly. It is paramount to use the functional unit of 1 kWh of multi-Si PV module output when evaluating lifecycle impacts to ensure comparability. 在使用中国多晶硅光伏模块的生命周期评估数据时，必须整合此库存数据中列出的从硅料到最终模块组装的完整生产过程中的材料消耗和环境排放。此外，用户应该考虑《中国太阳能光伏清洁生产报告》中的能耗基准。此数据集针对评估中国环境影响进行了优化，并应相应使用。在评估生命周期影响时，使用1 kWh多晶硅光伏模块输出的功能单位至关重要，以确保可比性。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 Jinfeng Yang, yjfzfshn@163.com 杨锦锋, yjfzfshn@163.com yjfzfshn@163.com yjfzfshn@163.com 2023-12-27T19:27:53+08:00 2024-04-20T14:58:40.884193+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=2dc92b19-b1f8-413b-b704-c4fd0a981fc4&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses Multi-Si solar cell,Multi-Si solar cell,Multi-Si solar cell Input 1090.0 1090.0 Measured Multi-Si solar cell Multi-Si solar cell Glass Input 63.26 63.26 Measured Glass Glass aluminium Input 11.77 11.77 Measured Aluminum Aluminum Polyethylene terephthalate Input 3.27 3.27 Measured Polyethylene terephthalate part (PET) Polyethylene terephthalate part (PET) Polyvinyl fluoride (PVF) Input 3.27 3.27 Measured Polyvinyl fluoride film (PVF) Polyvinyl fluoride film (PVF) Ethanol Input 0.05697 0.05697 Measured Ethanol Ethanol Ethylene-vinyl acetate copolymer,Ethylene-vinyl acetate copolymer,Ethylene-vinyl acetate copolymer Input 7.52 7.52 Measured Ethylene vinyl acetate copolymer (EVA) Ethylene vinyl acetate copolymer (EVA) Isopropanol Input 0.01767 0.01767 Measured Isopropanol Isopropanol freshwater Input 118.04 118.04 Measured Water Water process steam Input 16.22 16.22 Measured Steam Steam Electricity Input 72.0 72.0 Measured Electricity Electricity Solar Module,Solar Module,Solar Module Output 1000.0 1000.0 Measured Solar panels Solar panels Activated carbon Output 0.06111 0.06111 Measured Activated carbon (charged) for recovery Activated carbon (charged) for recovery Water (evapotranspiration) Output 94.26 94.26 Measured Water (evapotranspiration) emissions to air Water (evapotranspiration) emissions to air Water Output 23.78 23.78 Measured Water emissions to fresh water Water emissions to fresh water
