The technical and economic sustainability of photovoltaic (PV) systems is heavily affected by the cost and performances of the adopted PV cells. Solar concentrators represent an effective alternative to reduce the solar cell surface and, at the same time, to increase the global conversion efficiency. Such systems include optic elements to concentrate the solar radiation to a small area where hi...

The majority of incident solar irradiance causes thermalization in photovoltaic (PV) cells, attenuating their efficiency. In order to use energy on a large scale and reduce carbon emissions, efficiency must be enhanced. Effective thermal management can utilized generate additional electrical power while simultaneously improving this work, an experimental model hybrid photovoltaic-thermoelectric...

Cities import energy, which in combination with their typically high solar absorption and low moisture availability generates the urban heat island effect (UHI). The UHI, combined with human-induced warming, makes our densely populated cities particularly vulnerable to climate change. We examine the utility of solar photovoltaic (PV) system deployment on urban rooftops to reduce the UHI, and we...

In this study, the electrical and thermal efficiency of natural convection water-cooled photovoltaic panel (PV) is compared with standard PV module. modules are made up polycrystalline solar cells. As it known that, an increase in temperature results a decrease efficiency. The aim study to characteristic values such as air/PV temperature, radiation, voltage, current, power recorded for both pan...
