摘要

The solar photovoltaic (PV) panel waste has high potential to damage the earth and its resources if not carefully disposed. In this research, cement and coarse aggregate are partially replaced with functional layers (silicon wafer, ethylene vinyl acetate sheet, busbars, fingers) and glass of solar panels in M25 grade concrete. This method demonstrates that the recycling process can replace 11.69 billion tonnes of cement and 98.46 billion tonnes of gravel with materials derived from solar panels. The concretes manufactured have densities of 1860.91 kg/m3 and 1943.79 kg/m3, categorizing them as lightweight concretes. SEM and TEM analysis shows good hydration and bonding in the concrete. Brunauer–Emmett–Teller analysis demonstrates lightweight concrete has a surface area of 12.524 m2/g and 11.514 m2/g against 6.910 m2/g for conventional concrete. The lightweight concrete has thermal conductivities of 0.106 W/mK and 0.115 W/mK, compared to 0.295 W/mK for conventional concrete. After being cured in water and HCl acid, concrete cubes were subject to a compression test and they attained the designed strength. This research corresponds with the UN Sustainable Development Goals (7, 9, 12, 13, 15) by providing a sustainable and efficient strategy for solar waste management.
