What are the Challenges in Using Light Energy in Nanotechnology?
Despite the numerous advantages, there are several challenges in harnessing light energy in nanotechnology:
Stability Nanomaterials can be unstable when exposed to light for extended periods, leading to degradation of their properties. For instance, perovskite solar cells suffer from stability issues under prolonged light exposure.
Scalability Manufacturing nanomaterials on a large scale while maintaining their unique properties remains a significant challenge. Techniques like chemical vapor deposition (CVD) and molecular beam epitaxy (MBE) are complex and costly.
Toxicity The potential toxicity of nanomaterials, especially in biomedical applications, is a concern. Understanding the interaction of these materials with biological systems is crucial for their safe application.
