Abstract: An asymmetric compound parabolic concentrator (CPC) photovoltaic/thermal (ACPC-PV/T) solar collector with a double-pass air channel has the potential to enhance PVT performance for facade applications. Through outdoor experiments, we compared the ACPC-PVT with the symmetric CPC PV/T and conventional flat-type PV/T. The analysis shows ACPC PV/T exhibits superior energetic efficiency by 3.95% and 10.79% compared to symmetric CPC PV/T and conventional flat-type PV/T, respectively. Exergy analysis strengthens these findings, with overall exergy efficiency higher by 3.79% and 20.07%, respectively. Economic evaluation reveals a favourable 6.84-year payback for ACPC PV/T, the lowest among the three.
