چکیده

Photovoltaic module temperature is a detrimental parameter influencing the energy yield and durability of photovoltaic systems. Among passive strategies to reduce operating solar cells, radiative cooling receiving lot attention, as an effective mean passively evacuate heat in The existence wavelength window atmospheric transparency (8–13 μm) allows sending outer space. functionalization glass that could help limit or cells interesting approach. In this paper, we explore effect surface patterns its radiation performance, so be enhanced. study based on numerical simulations, calculating spectral emissivity different geometrical configurations structures top glass. Different figures micrometers size have been tested find optimal response transparent window. Periodical cones, pyramids, moth-eye shapes result responses close one along thermal wavelengths (8–25 which increases emitted power However, when assessing under sunlight, evaluation band has expanded (0.3–25 μm). Here, found not all are for cooling. Surfaces textured by holes pyramids show substantial effect, providing increase over flat ranging from 40 W/m2 110 depending devices.

Leakage Current Based Thermal Modeling of Glass Disc Insulator Surface

The stability of transmission lines relies on the health of the insulators, such as glass string insulators, which may occasionally flashover during an overvoltage. The likelihood of flashover increases notably when the glass insulator is wrapped by a wet contaminant layer. In this paper a study of the surface thermal profile of glass disc insulators insulation had been carried out for both cle...

The effect of SiO2 nanoparticle on the performance of photovoltaic thermal system: Experimental and Theoretical approach

The low conversion efficiency of solar cells produces large amounts of thermal energy to the cells, and with an increase in the temperature of solar cells, their electrical efficiency decreases. Therefore, a hybrid photovoltaic thermal system improves the overall efficiency of the system by adding thermal equipment to the solar cell and removing excessive heat from these cells. In this paper, w...
