A parametric study on the performance characteristics of an evacuated flat-plate photovoltaic/thermal (PV/T) collector (2020)
Journal Article
Hu, M., Guo, C., Zhao, B., Ao, X., Suhendri, Cao, J., Wang, Q., Riffat, S., Su, Y., & Pei, G. (2021). A parametric study on the performance characteristics of an evacuated flat-plate photovoltaic/thermal (PV/T) collector. Renewable Energy, 167, 884-898. https://doi.org/10.1016/j.renene.2020.12.008

An evacuated flat-plate photovoltaic/thermal (E-PV/T) collector was proposed. The inner space of the E-PV/T collector is vacuumed to suppress non-radiative heat losses, thus increasing thermal efficiency of the collector. Therefore, the E-PV/T collec...
