SYNTHESIS AND CHARACTERIZATION OF SILICA NANOPARTICLE AS COOLING MATERIALS FOR SOLAR PANELS
Silica nanoparticles are an essential nanofluid ingredient for absorbing heat in photovoltaic systems. Silica powder is extracted from geothermal sludge using the sol-gel method with acid-base treatment. The gel formed is stored at 12 and 18 h aging to control the particle size and microstructure.

Silica nanoparticles are an essential nanofluid ingredient for absorbing heat in photovoltaic systems. Silica powder is extracted from geothermal sludge using the sol-gel method with acid-base treatment. The gel formed is stored at 12 and 18 h aging to control the particle size and microstructure. XRD, FTIR, SEM, TEM and DSC were employed to characterize the resulting silica particles' microstructure, morphology and surface area. It is found that the silica nanoparticle contains a crystalline phase microstructure, with an average particle size of 40 nm, embedded in an amorphous matrix. The resulting silica nanoparticles meet the requirements and are suitable for forming nanofluids.
