Pengaruh Molaritas Dan Jumlah Siklus Dip-Drying Pada Sintesis Koating Tembaga…

Solar Selective Absorber (SSA) is the most important part that determines the efficiency of solar thermal collectors. SSA should have high absorptance (low reflectance at wavelengths 2.5 m). Solar selective absorber can be synthesized using sol-gel dip coating method. The purpose of this research is to know the effect variation molar of copper nitrate-cobalt nitrate and number of dipping-dryin…
