Sustainable Perovskite Recycling: A Nature study introduces a water-based method using sodium acetate, sodium iodide, and hypophosphorous acid to recycle Perovskite Solar Cells (PSCs), eliminating toxic organic solvents like dimethylformamide. This process recovers 99% of materials and maintains efficiency over five cycles.
Environmental Concerns with PSCs: Perovskite crystals contain toxic lead, posing environmental risks. Traditional recycling methods use harmful organic solvents.
India’s Solar Capacity & Goals: As of April 2025, India’s installed solar capacity is 105.65 GW. Target to reach 100 GW by 2030.
Key Initiatives: Rooftop Solar Programme supported by SUPRABHA and SRISTI; PM Surya Ghar Muft Bijli Yojana (PMSGMBY) has reached 10 lakh solar-powered homes.
Challenges: Land acquisition conflicts, infrastructure deficits, investment constraints, domestic manufacturing gaps, environmental impacts (solar waste), and limited battery storage capacity.
Solutions for Growth: Optimizing land use (agrivoltaics), grid modernization and energy storage, DISCOM reforms, circular economy for solar waste (recycling policy), enhancing domestic manufacturing (PLI scheme), and international collaboration (ISA).
Significance of New Recycling Method: The water based recycling method adresses one of the major concerns for Perovskite cells and paves way for low-cost high-efficiency solar technology.
