For instance, while perovskite solar cells have demonstrated impressive efficiencies in laboratory settings, their performance can degrade rapidly when exposed to moisture and UV radiation.
Researchers are actively working on encapsulation techniques and material formulations to enhance stability and ensure that these cells can withstand environmental stressors over extended periods. Another challenge lies in the scalability of production methods for advanced materials. While laboratory-scale synthesis may yield high-quality samples with excellent performance metrics, translating these processes to industrial-scale production remains complex.
Ensuring consistent quality and performance across large batches is critical for commercial viability. Additionally, regulatory hurdles related to the use of certain materials—such as lead in some perovskite formulations—pose significant challenges that must be navigated to gain public acceptance and regulatory approval.
