Carbon-Based Perovskite Solar Cells (CPSCs)

Carbon-Based Perovskite Solar Cells (CPSCs): Scientists have recently developed ethanol and ethyl acetate-based solutions to dissolve other components of perovskite solar cells.

• This method allows for recycling and reuse of all components, including perovskite crystals.
• About Carbon-Based Perovskite Solar Cells (CPSCs): First indigenous perovskite-powered niche product developed in India.

o Aims to enable stable and futuristic perovskite solar cells.

o Issues with Perovskite Photovoltaic Cells: Degrade on exposure to heat, moisture, light, and other environmental factors.

o Stability over long durations is a key challenge for commercial-scale deployment.

o CPSCs help reduce stability issues and fabrication costs.

o Humidity and thermal stress sensitivity of perovskite materials remain major barriers.

• Significance: Indigenously developed CPSCs may resolve stability concerns in PSCs.

o Can reduce fabrication costs and accelerate commercialization of perovskite-based niche products.

• About Perovskite: A material with the same crystal structure as calcium titanium oxide (CaTiO3). Discovered in 1839 in the Ural Mountains, named after Lev Perovski.

o General formula: ABX₃, where A and B are cations, X is an anion.

o Compositional flexibility allows wide-ranging electrical, optical, and physical properties—from insulating to superconducting.
