By employing a combination of analytical tools including lock-in thermography and
synchrotron-based x-ray fluorescence microscopy, transition metals have been identified at …

The efficiency of a solar cell is given by its average electrical parameters. On
inhomogeneous materials and especially on large-area solar cells the inhomogeneity of the …

Nine different types of shunt have been found in state‐of‐the‐art mono‐and multicrystalline
solar cells by lock‐in thermography and identified by SEM investigation (including EBIC) …

By applying lock-in thermography imaging, light-beam-induced current imaging, electron-
beam-induced current imaging at different stages of sample preparation, and infrared light …

Impurity and minority carrier lifetime distributions were studied in as-grown multicrystalline
silicon used for terrestrial-based solar cells. Synchrotron-based x-ray fluorescence and the …

In this study, we have utilized characterization methods to identify the nature of metal
impurity precipitates in low performance regions of multicrystalline silicon solar cells …

The efficiency of multicrystalline solar cells is limited by defects and impurities, which include
grain boundaries, dislocations, and transition metals. The density of these defects often …

In broad terms, this thesis is concerned with the measurement and interpretation of carrier
lifetimes in multicrystalline silicon. An understanding of these lifetimes in turn leads to a …

Lock-in thermography (LIT) is until now the most successful technique for imaging local
inhomogeneities of the dark forward and reverse current in solar cells and thus for …

Synchrotron-based analytical x-ray microprobe techniques were employed to study the
dissolution of iron, copper, and nickel silicide precipitates at structural defects in cast …
