PerovsJet inkjet coating system for perovskite solar cell R&D

Problem solved

Perovskite R&D labs struggle to evaluate ink formulations at small scale because production slot-die coaters require large ink volumes and commercial inkjet printers lack solvent resistance for perovskite precursors. PerovsJet bridges the gap with 0.5 mL minimum ink volume and full chemical resistance.

Application contexts

• Perovskite solar cell ink formulation development
• Thin-film process optimisation for large-area deposition
• Printed electronics R&D
• Organic semiconductor device prototyping

Technical principle

Uses Microjet's proprietary GlassJet piezoelectric single-nozzle head made of glass and Teflon contact surfaces, resistant to DMF, NMP, and other aggressive organic solvents. Programmable substrate heating (RT-105°C) with temperature profile control enables in-situ drying. Twin cameras monitor droplet flight and deposition. Compact footprint fits inside standard gloveboxes.

Typical use cases

• Perovskite ink formulation screening with <0.5 mL per iteration
• Process parameter optimisation (drop spacing, substrate temperature, drying profile) for perovskite layer quality
• Small-area (W70xD78 mm) perovskite cell prototype fabrication in glovebox environment
