Low-cost perovskite solar cells

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
