Q: What are Perovskite Solar Cells?

Perovskite Solar Cells are next-generation photovoltaic devices that use materials with a perovskite crystal structure to convert sunlight into electricity, offering higher efficiency and lower production costs than conventional silicon-based cells.

Q: Why are Perovskite Solar Cells considered revolutionary?

They combine high power conversion efficiency, flexibility, and low production costs, making them suitable for coating surfaces like windows, rooftops, and electronic devices.

Q: What is the main limitation of PSCs?

The biggest challenge is instability, they degrade rapidly under moisture, heat, and sunlight exposure. Additionally, the use of toxic lead raises environmental concerns.

About Perovskite Solar Cell (PSC)

A Perovskite Solar Cell (PSC) is a type of thin-film photovoltaic device that uses perovskite-structured compounds (ABX₃) as the light-absorbing active layer.
Perovskite Material:
- Named after the mineral calcium titanium oxide (CaTiO₃).
- General chemical formula: ABX₃, where ‘A’ and ‘B’ are cations and ‘X’ is an anion.
- In solar tech, it usually refers to metal halide perovskites: hybrid organic–inorganic compounds with a metal cation (Pb²⁺, Sn²⁺), halide anion (I⁻, Br⁻, Cl⁻), and organic cation (methylammonium, formamidinium).
Advantages:
- High power conversion efficiency (PCE) (over 25% in labs).
- Thin, lightweight, and flexible → can be applied on windows, buildings, smartphones, and vehicles.
- Low-cost fabrication compared to energy-intensive silicon processing.
- Potential use in tandem solar cells with silicon for even higher efficiency.
Efficiency Potential: It is known for high light absorption, excellent charge transport, and bandgap tunability and also achieved power conversion efficiencies (PCEs) above 25%, comparable to silicon cells.
