This paper discusses the effect of jet impingement of water on a photovoltaic thermal (PVT) collector and compound parabolic concentrators (CPC) on electrical efficiency, thermal efficiency and power production of a PVT system. A prototype of a PVT solar water collector installed with a jet impingement and CPC has been designed, fabricated and experimentally investigated. The efficiency of the system can be improved by using jet impingement of water to decrease the temperature of the solar cells. The electrical efficiency and power output are directly correlated with the mass flow rate. The results show that electrical efficiency was improved by 7% when using CPC and jet impingement cooling in a PVT solar collector at 1:00 p.m. (solar irradiance of 1050 W/m² and an ambient temperature of 33.5 °C). It can also be seen that the power output improved by 36% when using jet impingement cooling with CPC, and 20% without CPC in the photovoltaic (PV) module at 1:30 p.m. The short-circuit current of the PV module experienced an improvement of ~28% when using jet impingement cooling with CPC, and 11.7% without CPC. The output of the PV module was enhanced by 31% when using jet impingement cooling with CPC, and 16% without CPC.
本文讨论了水的喷射冲击对光伏光热（PVT）集热器以及复合抛物面聚光器（CPC）在PVT系统的电效率、热效率和发电量方面的影响。已设计、制造并对安装有喷射冲击装置和CPC的PVT太阳能集热器原型进行了实验研究。通过利用水的喷射冲击来降低太阳能电池的温度，可以提高系统的效率。电效率和功率输出与质量流量直接相关。结果表明，下午1点（太阳辐照度为1050 W/m²，环境温度为33.5°C）时，在PVT太阳能集热器中使用CPC和喷射冲击冷却时，电效率提高了7%。还可以看出，下午1:30时，在光伏（PV）模块中使用CPC进行喷射冲击冷却时，功率输出提高了36%，不使用CPC时提高了20%。使用CPC进行喷射冲击冷却时，PV模块的短路电流提高了约28%，不使用CPC时提高了11.7%。使用CPC进行喷射冲击冷却时，PV模块的输出提高了31%，不使用CPC时提高了16%。
