研究目的
To evaluate the performance of the concentrated solar spectrum splitting photovoltaic (PV) cell-gas turbine (GT) hybrid system and predict the maximum efficiency.
研究成果
The model of the concentrating spectrum splitting PV-GT system has been established, and the performance of the SSS is evaluated and optimized by means of numerical calculation. The maximum efficiency of the SSS can reach up to 52.3% when the collector temperature, voltage output, band gap energy, area ratio of the collector to the PV cell, and solar concentration factor are optimized. The efficiency of the SSS is markedly higher than that of the single CPV cell or solar-powered GT.
研究不足
The technical and application constraints of the experiments, as well as potential areas for optimization, are not explicitly mentioned in the abstract.
1：Experimental Design and Method Selection:
A model of the concentrated solar spectrum splitting PV cell-GT hybrid system is established. The cell voltage, collector temperature, and cutoff energy in the system are optimized.
2：Sample Selection and Data Sources:
The system includes the concentrator, splitter, solar heat collector, heat exchanger, PV cell, and GT.
3：List of Experimental Equipment and Materials:
The working fluid is ideal gas, and the heat transfer between the working fluid and the heat reservoirs follows the Newton law.
4：Experimental Procedures and Operational Workflow:
The concentrated sunlight is divided into two segments by the splitter based on the band gap. The photons with energy in excess of the band gap are sent to the PV cell, and the rest photons with energy below the band gap are sent to the collector.
5：Data Analysis Methods:
The efficiency and power density are expressed and optimized by means of numerical calculation.
