Main Article Content
Abstract
Cadmium Telluride (CdTe) quantum dots have garnered significant attention in the fields of solar cells and laser applications due to their unique optical and electronic properties. These nanomaterials, with their tunable band gaps and high absorption efficiency, present a promising avenue for enhancing the performance of solar cells and lasers. In the context of solar energy, CdTe quantum dots offer the potential for improved efficiency in photovoltaic devices by enabling better light absorption and carrier transport. In laser technologies, CdTe quantum dots are explored for their ability to operate at lower thresholds and generate more coherent light compared to traditional materials. However, challenges such as material instability, cost, scalability, and the toxicity of cadmium must be addressed to realize their full potential. This paper provides a comprehensive overview of the advancements in CdTe quantum dot-based solar cells and lasers, highlighting both the significant breakthroughs and the ongoing challenges. Future prospects for overcoming these hurdles are also discussed, emphasizing the role of CdTe quantum dots in next-generation energy and optoelectronic applications.
