Indoor experimental analysis of Serpentine-Based cooling scheme for high concentration photovoltaic thermal systems

High concentration photovoltaic thermal hybrids are expected to play an important role in meeting growing energy demands. When approaching concentrations over 1000 suns, a cooling system is needed maximise both the and electrical performance of multi-junction solar cell without producing excessive parasitic losses. This study develops novel simulation model provides in-depth understanding functionality concentrated hybrid with serpentine-based systems. An ultra-high concentrator optic irradiance profile (peak effective ratio: ∼1500 suns) considered within model, which has been validated through indoor experimentation. The effectiveness also evaluated maximum stresses generated cell. double serpentine design was deemed highest performing, primarily because single serpentine’s pressure drop. Copper as heat sink material yielded superior its higher conductivity. total exergetic efficiency achieved by receiver ∼10.9% this configuration. Compared some examples literature value may seem low, however, it more accurate due inclusion specific profile. All systems could maintain recommended operating temperature.
