Why in news
Japan is developing ultra-thin, flexible perovskite solar cells to integrate solar power into everyday items like clothing and vehicles to overcome space constraints.
Background
Japan's Agency for Natural Resources and Energy (ANRE) supports the development of perovskite cells. These cells are printed using techniques similar to newspaper printing and are designed to be flexible and ultra-thin compared to traditional silicon panels.
Facts for Prelims
- S&TPerovskite solar cells: A next-generation photovoltaic technology using perovskite-structured compounds.
- BodyANRE: Agency for Natural Resources and Energy (Japan) supports the development of these solar technologies.
- FactCommercialization target: Japan plans to commercialize perovskite cells over a decade-long timeframe.
For Mains
Q. Discuss how the development of flexible perovskite solar cells can address the challenges of urban energy density and decentralized power generation in densely populated regions.
Dimensions to cover in your answer
- Material durability: Addressing the degradation of perovskite structures under prolonged environmental exposure and moisture.
- Manufacturing scalability: Transitioning from newspaper-printing techniques to high-volume industrial production for diverse surfaces.
- Supply chain dependency: Managing the reliance on specific raw materials like iodine for large-scale perovskite production.
