Fang Yi, Peng Jinqing, Tan Yutong, et al. STUDY ON THERMOELECTRICITY PERFORMANCE OF BIFACIAL PHOTOVOLTAIC BLINDS INTEGRATED DOUBLE SKIN FAÇADE[J]. 2025, 46(3): 280-290. DOI: 10.19912/j.0254-0096.tynxb.2023-1772.
This paper introduced a novel approach by combining the bifacial photovoltaic blinds with a double skin façade
resulting in a bifacial photovoltaic blinds integrated double skin façade (bPVB-DSF). To evaluate the performance of bPVB-DSF
a numerical model was established and validated through experiments. Additionally
a sensitivity analysis was conducted to identify the key parameters that significantly influence the performance of the bPVB-DSF. Finally
the thermoelectric characteristics of different types of curtain wall systems were compared. The research findings demonstrated a high level of consistency between simulated and measured results
with root mean square errors of 1.32 ℃
1.49 ℃
and 0.66 ℃ for outdoor side glass
bifacial photovoltaic blinds
and indoor side glass temperatures
respectively. Based on the validated numerical model
the sensitivity analysis revealed that the tilt angle
blade width
blade spacing and facade orientation of the bifacial photovoltaic louvers have a greater impact on the thermoelectric performance of the system
while the influence of cavity spacing is minimal. In summer
the bPVB-DSF exhibited a 17.38% reduction in heat gain compared to the double skin façade (DSF). Additionally
when compared to the mono-facial photovoltaic blinds integrated double skin façade (mPVB-DSF)
the bPVB-DSF displayed an 11.35% increase in power generation
with negligible differences in thermal performance.
