Airbrush Spray Coating of Amorphous Titanium Dioxide for Inverted Polymer Solar Cells
Figure 1
Optical images of realized on glass/FTO substrate with 4 sprays at different TTIP concentration in 2-isopropanol: (a) 1%, (b) 2%, and (c) 5%. In case of (d), that corresponds to a 5% concentration with 8 sprays, white powder formation is observed.
