'Another factor to consider is the grain boundaries in polycrystalline solar cells.
It's been reported the occurrence of hydrogen induced inter-granular or transgranular quasi-cleavage fracture largely depends on tramp element (P, Sb, Sn, As) segregation to grain boundaries and the subsequent loss of grain boundary cohesive strength.
The local pinning of grain boundaries is counterbalanced by high grain boundary diffusivity due to local Joule heating' [13].

In addition, the solder bulk showed many cracks along the [beta]-Sn grain boundaries after isothermal aging when the content of SAC paste was 5 wt.%.
Similarly, Jodan Khatta samples show more alteration along their grain boundaries which also have affected their grain to grain relationship and thus have influenced their strength values.
Magnetization of a very small area plays an important role in some cases, such as those involving defects, dislocations, or grain boundaries. The spatial resolution is thus important for microscopic magnetization analysis.
We should consider the possible role of grain boundaries on inducing FM, as our structural characterization of the solgel-doped ZnO films [24] indicates a small grain size of about 20 nm.
This method reduces individual particle sizes in a polycrystal and consequently raises the density of grain boundaries (GBs).
The particles observed in the grain interiors and grain boundaries are MC-type carbides, such as (Ti,Mo)C; Cr-rich carbides (presumably [M.sub.23][C.sub.6]) precipitated preferentially in interdendritic regions and grain boundaries.
The UFG microstructure produced by severe plastic deformation has a high density of nonequilibrium grain boundaries, which are characterized by excess grain boundary energy and the presence of long-range elastic stress due to a large number of dislocations [3, 4].
