Low-cost perovskite solar cells

Santhosh Kumar 18/07/2023

Low-cost perovskite solar cells upsc notes
Context
Indian scientists' development
At International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), Hyderabad
Developed Carbon-based perovskite solar cells (CPSCs)
Advantages of CPSCs
High stability
Low cost
Suitable for large-scale commercialization
What are Perovskite solar cells (PSCs)?
Definition
Solar cell type
Use of perovskite materials
Light to electricity conversion
Commonly used perovskite
Methylammonium lead iodide (MAPbI3)
Issues with PSCs
Stability issues
Exposure to heat
Moisture
Other environmental factors
Solution
Engineered MaPbI3
Enhanced thermal stability
Guanidinium iodide (GuI) incorporation
Enhanced moisture stability
5-amino valeric acid iodide (5-AVAI) for surface passivation
Resultant benefits
Stability concern resolution
Reduced fabrication costs
Accelerated commercialization potential
Significance of PSCs
Recent attention gain
Potential to revolutionize solar energy
Low-cost manufacturing
High efficiency
Flexible substrate printing

Small Modular Reactors (SMRs) upsc notes 1. Definition and advantages Advanced nuclear reactors Capacity up to 300 MW Simplicity, safety, cost-effectiveness Factory-made, transportable Economical, time-efficient Longer refueling intervals 2. India's nuclear power status 22 nuclear reactors 7 power plants 6780 MW nuclear power Goal: 10% nuclear power by 2035 3. Global status of SMRs 70+ SMR designs 17 countries Examples NuScale Power (U.S.) Akademik Lomonosov (Russia) Rolls-Royce (U.K.) 4. India's need for more nuclear power Limited hydropower growth potential Coal capacity: 210 GW, 73% electricity Environmental concerns Intermittent wind and solar power 5. India's strategy Transition to SMRs Public-private partnerships Raise nuclear power to 10% by 2035 6. Niti Aayog's suggestions Encourage private sector participation Implement regulatory changes for safety Modify foreign investment policies 7. Way ahead for India Move towards passive safety designs Enforce nuclear liability End NPCIL monopoly in reactor operations 8. Conclusion Achieve net zero by 2070 Need 100 GW nuclear power by 2050 Portfolio of technologies, including SMRs Safe and cost-effective nuclear power
