Photovoltaic panels generate electricity from solar energy based on the photovoltaic effect. The conversion efficiency of photovoltaic panels depends on many factors such as solar radiation, wind speed, dust, orientation, tilt angle, and operating temperature. When the operating temperature increases by 1 °C, the conversion efficiency of photovoltaic panels decreases by 0.4% - 0.5%. Heat sink is a device used to cool electrical and electronic equipment, including photovoltaic panels. This paper presents calculating the cooling capability of hybrid heat sink made from two materials in steady state using heat transfer theory. Heat sink base is constructed from aluminum and copper layers, with copper layer thickness is 1 and 2 mm. Under different conditions of radiation intensity, wind speed, and tilt angle of photovoltaic panel, results show that heat sink added copper layers of 1 and 2 mm, the operating temperature decreases by about 0.6 K and 1.2 K compared to the aluminum base. Accordingly, the conversion efficiency of photovoltaic panel increased by 0.1% and 0.2%.

The addition of a heat sink to the back of the PV panel enhances convective heat transfer, improving its cooling capability.Heat sinks with bases composed of copper and aluminum layers demonstrate superior cooling performance compared to aluminum heat sinks alone, due to coppers higher thermal conductivity.The study reveals that incorporating copper layers with thicknesses of 1 and 2 mm into the heat sink base reduces the operating temperature of the PV panel by approximately 0.2 K, respectively, relative to an aluminum base, leading to a corresponding increase in conversion efficiency of 0.

Penelitian lebih lanjut perlu dilakukan untuk menguji secara eksperimental efektivitas pendinginan hybrid material heat sink dalam kondisi lingkungan yang sebenarnya, termasuk variasi radiasi matahari, kecepatan angin, dan suhu sekitar. Studi komparatif dapat dilakukan untuk mengevaluasi kinerja berbagai konfigurasi lapisan tembaga dan aluminium pada heat sink, dengan mempertimbangkan faktor-faktor seperti biaya material dan kemudahan fabrikasi, untuk mengoptimalkan desain heat sink. Selain itu, penelitian dapat difokuskan pada pengembangan model prediktif yang lebih akurat untuk memprediksi kinerja pendinginan heat sink berdasarkan parameter desain dan kondisi operasi, yang dapat membantu dalam perancangan sistem PV yang lebih efisien dan andal. Penelitian lanjutan juga dapat mengeksplorasi penggunaan material baru atau lapisan pelapis pada heat sink untuk meningkatkan kemampuan perpindahan panas dan mengurangi biaya produksi, serta menginvestigasi potensi integrasi heat sink dengan teknologi lain seperti pendinginan cair atau pendinginan termoelektrik untuk mencapai peningkatan kinerja yang lebih signifikan.
