A simulation of solar photovoltaic thermal system with spiral design absorber using MWCNT water working fluid

The photovoltaic (PV) module's temperature distribution is not even in most cases, which causes a region of hotspots to appear in some areas. Due to these hotspots, less effective cell performance causes declination in overall efficiency of PV systems. Due to this, temperature uniformity is dis...
