About Photovoltaic Energy StorageSelf-healing is a process by which the capacitor restores itself in the event of a fault in the dielectric which can happen during high overloads, voltage transients, etc. When insulation breaks down, a short duration arc is formed (figure 1)
About Photovoltaic Energy StorageThe gel with flexible molecular chains probably rendered self-healing property by exploiting the reversible bonds. As a result, gel is an ideal candidate as self-healing material. In addition, most of the literatures state that the applicability of the self-healing gel is greatly limited because the mechanic strength is not generally ideal [15].
