Photovoltaic cell module heat dissipation
Heat Effect on Silicon PV Modules
Congestion appears either in the encapsulating polymer on the back side of the module thus forming the bubbles if this happens on the back side of module. The heat dissipation properties of the cell are reduced, increasing overheating and thus causing a reduction in the lifetime of the module (Figs. 10 and 11). (b) Water Cooling of PV modules.
