Crystalline silicon heterojunction with intrinsic thin-layer photovoltaic (HIT-PV) module produces more output power, compared with the c-Si photovoltaic module. However, it presents a risk of overheating in hot weather. In this paper, we used a new cooling design of the heterojunction with intrinsic thin-layer photovoltaic thermal (HIT-PVT) module to lower the temperature using laminated encapsulation of an aluminum collector in outdoor climates. The measured electrical, thermal and total efficiencies of a HIT-PVT system can catch up to 17.47%, 34.71% and 52.18%, respectively. Moreover, comparing with HIT-PV module, the output power of the HIT-PVT module was enhanced by 5.58% with coolant circulation, and the converted electrical energy can be increased by 9.81% with the designed HIT-PVT module. In addition, the primary energy savings of the new HIT-PVT and HIT-PV systems were 79.77% and 43.71%, respectively.

具有铝集热器的基于本征薄层太阳能电池的异质结的增强电性能光伏热系统


与晶硅光伏组件相比，具有本征薄层光伏组件的晶体硅异质结（HIT-PV）组件可产生更多的输出功率。然而，它在炎热的天气中存在过热的风险。在本文中，我们采用了一种新的异质结冷却设计和本征薄层光伏热（HIT-PVT）模块，以在户外气候下使用铝集热器的层压封装来降低温度。实测HIT-PVT系统的电效率、热效率和总效率分别可达17.47%、34.71%和52.18%。此外，与HIT-PV模块相比，通过冷却剂循环，HIT-PVT模块的输出功率提高了5.58%，所设计的HIT-PVT模块的转换电能可提高9.81%。此外，新型HIT-PVT和HIT-PV系统的一次能源节省分别为79.77%和43.71%。
