Abstract

• HFHP heat sink lowers solar cell temperature by 20.93% at 2500 W/m 2 irradiance vs. PRF design. • Hexagonal and rhombus perforations enhance airflow, boosting heat transfer and cooling efficiency. • HFHP fin design increases electrical efficiency by up to 0.48% at 1000 W/m 2 irradiance. • Nusselt number rises by 62.49% for HFHP at 1 m/s, indicating superior convective heat transfer. • Overall thermal resistance is lowest in HFHP, enabling more effective heat dissipation from solar cells.
