Close examination of localized hot spots within photovoltaic modules
If define each cell in a module (for example a PV module of 60 cells) as 1 unit, then the module contains 60 units. And most researches focus on 1 or more units of the 60(i.e., the large-scale hot-spot phenomena, as mentioned above), while few researches focus on the smaller scale than 1, i.e., the localized hot-spot phenomena within a unit cell.
