A lab-to-fab study toward roll-to-roll fabrication of reproducible perovskite solar cells under ambient room conditions. Cell Rep. Phys. Sci. 2, 100293 (2021). Kim, J. E. et al. Slot die coated planar perovskite solar cells via blowing and heating assisted one step deposition.
There are some other film forming methods that qualify as exotic but have been used to form some of the layers in polymer solar cell stacks. One such method is double slot-die coating which is possible at much lower web speeds and on a much smaller scale than curtain and slide coating, and also allows for a much simpler control of the ink flow.
For polymer and organic solar cells, the possibility of solution processing has overturned this picture, and the wide selection of printing and coating techniques available may end up being what defines polymer solar cell technology.
