Description
Summary:Take PERC P-type monocrystalline silicon and PERC P-type polycrystalline black silicon modules as examples to establish a life cycle carbon emission inventory of crystalline silicon modules. Study the contribution of five recycling technologies to the life cycle carbon emission reduction of two crystalline silicon modules, and the impact of the life cycle of 1MWP PERC P-type monocrystalline silicon and PERC P-type polycrystalline black silicon module systems on the environment. The results show that the carbon emissions of the two photovoltaic systems are concentrated in the production stage, and the carbon emissions of the crystalline silicon purification process are the highest, accounting for more than 41%. Through green low-carbon recycling technology to process waste photovoltaic modules to obtain glass, aluminum, silicon and other materials to achieve resource recycling, it can reduce the energy consumption of the module production process and life cycle carbon emissions. According to calculations, 1 MWp PERC P-type monocrystalline silicon system has 10% higher life cycle carbon emissions than PERC P-type polycrystalline black silicon system.
