Influence of Different Types of Recombination Active Defects on the Integral Electrical Properties of Multicrystalline Silicon Solar Cells

Figure 1

(a) Electroluminescence image (EL) of a mc-Si solar cell. The recombination active defects (visible due to their decreased EL signal) can be separated by an image processing procedure described in [9] into the lateral distribution of Type-A (purple) and Type-B (orange) defects shown in (b).
