The spectrum splitting system (SSS) is an efficient approach to relieve the energy losses in the solar cell and boost the efficiency of solar energy utilization. A model of the concentrated solar spectrum splitting photovoltaic (PV) cell‐gas turbine (GT) hybrid system is established to evaluate the performance of the system and predict the maximum efficiency. The numerical calculations show that the area ratio of the solar collector to the PV cell significantly affects the maximum efficiency of the spectrum system, but most of the previous studies are not considered. The maximum efficiency of the system is 50.6% when the parameters including the cell voltage, collector temperature, and band gap energy of the PV cell are optimized at the same areas of the collector and PV cell. The proposed SSS can achieve the maximum efficiency of 52.3% when the area ratio of the collector to the PV cell is further optimized. The results obtained are compared with those of a single concentrating PV cell or solar‐powered GT, and consequently, the advantages of a concentrating spectrum splitting PV cell‐GT hybrid system are revealed.

频谱分裂聚光光伏电池-燃气轮机系统的优化和最大效率

频谱分割系统（SSS）是减轻太阳能电池中能量损失并提高太阳能利用效率的有效方法。建立了集中式太阳光谱分裂光伏（PV）电池-燃气轮机（GT）混合系统的模型，以评估系统的性能并预测最大效率。数值计算表明，太阳能集热器与PV电池的面积比显着影响光谱系统的最大效率，但以前的大多数研究都没有考虑。当在收集器和PV电池的相同区域优化包括电池电压，收集器温度和带隙能量在内的参数时，系统的最大效率为50.6％。建议的SSS可以达到52的最大效率。当集电体与PV电池的面积比进一步优化时为3％。将获得的结果与单个集中式光伏电池或太阳能GT的结果进行比较，因此，揭示了集中式光谱分裂PV电池-GT混合系统的优势。
