研究目的
Investigating the application of luminescence spectroscopy in new materials for solar energy utilization, focusing on luminescent solar concentrators (LSCs) and methods to increase their efficiency.
研究成果
The study concludes that luminescent solar concentrators (LSCs) have the potential to significantly reduce the cost of photovoltaic electricity by minimizing the amount of solar cells needed. The efficiency of LSCs can be improved by using materials with no overlap between absorption and emission, such as lanthanide complexes or proton transfer compounds, and by enhancing luminescence through surface plasmons. Future research should focus on optimizing these materials and methods for practical applications in solar energy utilization.
研究不足
The main limitations include the low efficiency of LSCs due to self-absorption of luminescent dyes and the escape of luminescence emitted beyond the critical angle. Additionally, the thermal and mechanical stability of organic matrices poses challenges for practical applications.
