The Qinghai-Tibet Plateau is rich in solar energy, with annual solar radiation amount of above 5400 MJ/m 2 . Owing to its effectiveness, renewability, safety and eco-friendliness, solar energy has been extensively utilized to generate electricity and provide heating for plateau buildings with abundant sunlight , .
The power conversion efficiencies (PCEs) of polycrystalline perovskite solar cells (PC–PSCs) have now reached a plateau after a decade of rapid development, leaving a distinct gap from their Shockley-Queisser limit. To continuously mitigate the PCE deficit, nonradiative carrier losses resulting from defects should be further optimized.
Therefore, photovoltaic (PV) power generation systems have become a promising solution to provide energy for buildings in rural areas by harvesting sunlight and converting it into electricity through solar arrays.
The working efficiency of the entire system can be calculated using the monitored real-time data on solar irradiance intensity and power generation, thus determining the comprehensive conversion efficiency of the photovoltaic power generation system, denoted as ηz.
The working efficiency and the comprehensive conversion efficiency of the PV system can reach as high as 16.6 % and 84.1 %, respectively. In March, the photovoltaic self-consumption rate of PV power by the building reaches as high as 93.2 %, effectively reducing the solar energy discarding.
Currently, solar thermal systems have been extensively applied for centralized heating in cities of Qinghai-Tibet Plateau , , . However, the characteristics of rural households located in Qinghai-Tibet Plateau significantly differ from those of urban buildings.
