Despite the promising advantages, there are several challenges: 1. Stability and Durability: Some nanomaterials, like perovskites, can degrade under environmental conditions, affecting their long-term performance. 2. Scalability: Producing nanomaterials on an industrial scale while maintaining quality and consistency is challenging. 3. Cost: Although nanotechnology can reduce costs in the long run, the initial investment in research and development can be high. 4. Regulatory Issues: The use of nanomaterials is subject to regulatory scrutiny, especially concerning environmental and health impacts.
