Low-cost selective deposition of wax onto textured solar cells
The active regions of a solar cell must be inoculated with wax, while leaving the metal fingers and bus bars bare, in preparation for the electroplating step of a new solar panel manufacturing process. Different methods to achieve the inoculation of the cell are discussed, along with their …

Nucleation inhibition and enhancement in chemical vapor deposition
Area selective deposition (ASD) is becoming increasingly attractive as a bottom-up approach to nanomanufacturing. Most ASD processes developed so far concern selective deposition of metal on metal (i.e., not on non-metallic surfaces) or oxide on oxide (i.e., not on metallic surfaces), but …
