Outline
Introduction Spray Deposition Technique Nanocrystalline Ink Synthesis Conclusion
Introduction The synthesis and implementation of
nanocrystalline particles.
Focus on Cu( or (CIGS) nanocrystals, as the active light absorbing material in PVs devices.
Spray Deposition(SD) Technique.
Spray deposition by using an Airbrush.
Spray deposition by using Robotic Sprayer .
Spray Deposition Technique
• Precise control over film thickness
• Using of flexible, inexpensive and light-weight
plastic substrates.
• Can be readily applied to larger substrates.
• Very effective and efficient nanocrystal
deposition approach.
Why Spray Deposition Technique ?
• The synthesis reaction equation of CIGS :
• ƞ ≈ 3.1 % on glass substrates (2012)
• ƞ ≈ 2 % on plastic substrates
• ƞ > 12 % has been achieved by converting Cu(In,Ga)Se2 NC to Cu(In,Ga)(S,Se)2 via selenization at 500 C.
Nanocrystal Ink Synthesis

Relatively low efficient PVs for commercialization.
High temperature selenization lead to higher
efficiency.
Thin films deposition of inorganic materials
under ambient conditions.
Plastic PVs can be fabricated.
