研究目的
Investigating the performance improvement of trough concentrating photovoltaic thermal system by optimizing different components and operating parameters.
研究成果
The performance of TCPV/T systems can be improved by optimizing components such as PV cells (preferably triple junction GaAs cells), increasing concentrator reflectivity, and selecting efficient receiver shapes (rectangle and triangle). These optimizations can lead to increased electrical and thermal efficiencies, enhancing the overall energy production of the system.
研究不足
The study is based on a review of existing literature and does not present new experimental data. The performance improvements are theoretical and depend on the optimization of components and parameters.
