What are the Challenges Facing Thin Film Solar Cells?
Despite their numerous advantages, thin film solar cells also face several challenges: - Efficiency: Generally, thin film solar cells have lower efficiency compared to traditional silicon solar cells. However, ongoing research in nanotechnology aims to bridge this gap. - Stability and Longevity: Some materials used in thin film solar cells can degrade over time, affecting their performance and lifespan. - Toxicity and Environmental Impact: Certain materials, such as cadmium in CdTe, pose environmental and health risks, necessitating careful handling and disposal.
