Short course on

Electrical characterization of multijunction solar cells 

The electrical  behaviour of multijunction solar cells (MJSCI) cells is inherently different than that of conventional single junction (SJ)  due to the internal series connection of several junctions with different band-gaps. This short course will focus on special attention should paid to the electrical  characterization of MJSCI based on current-voltage characteristic (I–V curve) under dark conditions and under illumination, electroluminescence and spectral response/quantum efficiency characterization of MJ solar cells. The fundamentals of these techniques, as well as the intricacies of their application to MJSC will be reviewed in this webinar, with particular attention to addressing the challenges required to appropriately measure state of the art devices, e.g. metamorphic triple-junction cells, 4-junction MJSC, etc.
