Use advice for data set When employing this LCA dataset for solar-grade multi-Si, it is important to ensure that the scope and boundaries of the analysis match the dataset's specifications. This includes proper accounting for energy and resource inputs as well as environmental emissions during the life cycle stages. Special attention should also be paid to the geographical relevance (as the data is specific to Sichuan Province, China) and the technology level represented. The data should not be generalized beyond the production practices of the specified solar cell manufacturer without careful consideration of technological and process variations.
Technical purpose of product or process This dataset relates to the manufacturing process of solar photovoltaic (PV) cells using multi-crystalline silicon (multi-Si) semiconductor technology. The solar PV cells produced by this process are typically used in the fabrication of solar panels which convert sunlight into electricity. These panels are employed in various applications ranging from residential and commercial solar installations to large-scale photovoltaic power stations.
