Renewables are set to form the backbones of our future energy system and among them, photovoltaics (PV) has rapidly become one of the most economic energy generation technology. The price of electricity generated by PV has reached a levelized cost of electricity of 5-10 €c/kWh, leading to a major acceleration of its deployment with over 110 GWp of newly installed capacity in 2019 alone. The cumulative installed PV capacity is now 627 GWp and it is expected to reach over 1 TWp by 2025 as predicted by the IEA PVPS. The PV market is largely dominated by crystalline silicon (c-Si) PV modules representing 95% of the market share, while thin-film modules remain a niche product. The Terawatt Era of PV modules is approaching fast, and it is raising important questions about end-of-life management as 5 million tons of PV waste by 2030 is projected by IRENA. Embracing a circular economic model for this maturing industry brings a major opportunity to make sure that PV becomes one of the most sustainable sources of energy.
