Fig. 6.13 Sketches showing the monolithic interconnection scheme, for connecting individual
amorphous silicon solar cells (deposited on glass) to form an entire module: a General principle—
Abbreviations used: photo-active cell width w; photo-inactive interconnection width Transparent Conductive Oxide TCO. b Details of the current flow—Abbreviations used: current density

Dust Particle
(Shunt created after
dust particle falls off)
Fig. 6.14 Sketch showing the formation of a shunt within the solar cell, by a dust particle present
during deposition. Reproduced from [1], with the kind permission of the EPFL Press
6. Is very sensitive to the presence of dust and other particles
Figure 6.14 shows what happens, if dust particles are present → Shunts will be
created in the cells.
6.2.3 Properties of Amorphous Silicon Solar Cells
The main properties of a-Si:H solar cells and modules can be summarized as follows:
