Description
This dataset describes the physical dismantling and treatment of 1 kg of used crystalline silicon single glass photovoltaic modules, based on the calculation of 28.6 kg and 530 Wp of each crystalline silicon single glass photovoltaic module. The data is taken from China's photovoltaic module recycling demonstration project. Infrastructure such as equipment manufacturing and plant construction for dismantling and processing are not included within the boundaries of the data set. The physical method is used to process all parts of crystalline silicon photovoltaic modules, mainly including pretreatment, frame treatment, output end treatment, glass treatment, backplane treatment, film treatment, welding tape treatment, and battery treatment. Among them, the pretreatment adopts sorting, cleaning and drying; the frame treatment and the lead-out end treatment are dismantled manually or mechanically; Glass treatment adopts physical methods such as heating, high-pressure peeling, and cutting. Physical methods such as back plate treatment, film treatment, welding tape treatment, and battery treatment are adopted, such as shearing, low-temperature grinding, vibration screening, floating sorting, and centrifugal sorting.
