摘要：
In this study a new method which treats opaque cells and transparent glass separately is proposed for simulating the effect of different solar cell widths on the daylighting performance of semi-transparent photovoltaic (STPV) windows. Experiment was conducted to validated against the simulation model. According to the difference between simulation results and experimental data, both the illuminance and Daylight Glare Probability (DGP) obtained by the proposed method are significantly better than those of the traditional method. Detailed simulation of the daylighting performance of three semi-transparent PV windows with the same PV coverage but different cell widths of 2.5 mm, 5.0 mm, 7.5 mm are further conducted based on the proposed method. Both the daylighting and glare performance of the STPV windows are analyzed and compared in terms of four typical indicators including Daylight Autonomy (DA), Useful Daylight Illuminance (UDI), Daylight Glare Index (DGI), and Daylight Glare Probability (DGP). The results show that with the increase of cell width, the average DA, UDI and indoor visual comfort gradually decrease, while the probability of glare increases. The proposed method in this paper makes it possible to simulate the daylighting and glare performance of STPV windows with different cell widths, and the best cell width is obtained via this method © 2022, Solar Energy Periodical Office Co., Ltd.
