研究目的
To design and prototype a micro-prism-based spectrum splitting concentrator optics for lateral-arrayed multi-junction micro CPV modules that achieves high optical transmission and efficient spectrum splitting with minimal beam deflection.
研究成果
The micro-prism-based spectrum splitting concentrator optics demonstrates high transmission and efficient spectrum splitting with minimal beam deflection, making it suitable for cost-effective micro CPV module assembly. Future improvements in manufacturing and assembly processes could further enhance performance.
研究不足
The current prototype achieves ~80% transmission with anti-reflection coatings, with potential for improvement in manufacture and assembly processes to reach ~90% transmission. The design may face challenges in scaling up for large-scale production.
