Use advice for data set | When using the LCA dataset for multi-Si PV modules, it is essential to average the values provided by the multiple data sources if discrepancies exist. Consider the data gathered from literature, environmental impact assessment statements, and industry reports. Ensure that the appropriate environmental impact assessments are chosen based on the geographic relevance of the product lifecycle under consideration. Remember to account for any methodological differences between sources and apply consistent system boundaries. |
Technical purpose of product or process | Thermal treatment of Ethylene-vinyl acetate (EVA) refers to the process necessary for the preparation of EVA for use in multi-Si photovoltaic (PV) module assembly. Pre-treated EVA, along with remelted glass and chemically treated aluminum and silicon, is used as a substitute for virgin materials in manufacturing these modules. Additionally, pre-treated EVA is crucial in the recycling process of multi-Si PV cells to ensure the efficient recovery of materials and components. |

General comment on data set | Glass need to be remelted, EVA (Ethylene Vinyl Acetat) need thermal treatment, and aluminum need remetling and chemical treatment before they may substitute virgin materials in the module assembling process. Meanwhile, chemical treatment is necessary for silicon and silver before recycling in polysilicon production and multi-Si PV cell respectively. |

Data selection and combination principles | The inventory data of the multi-Si PV modules are collectedfrom several sources: (1) Literatures including Fu (2013), whichcontain material inventory of several photovoltaic enterprises inJiangsu province; Diao and Shi (2011), which contain materialinventory of two photovoltaic enterprises in Beijing; He (2013),which contain material inventory of four photovoltaic enterprisesin Gansu and Sichuan province. (2) Environment Impact Assessment Statements (EIAS) of multi-Si PV production companies fromSichuan (EIAS-Sichuan, 2008), Henan (EIAS-Henan, 2009) andChongqing (EIAS-Chongqing, 2008). (3) Industry report of marketforesight and investment prospect for China’s photovoltaicdevelopment (2014) and Industrial report of market foresightand investment prospect for China’s polysilicon development(2014). The mean value is applied when there are different datasources for specific materials. | ||||
