This poster will detail the optimisation of materials and development of formulations suitable for use at scale in slot-die coating processes used in the manufacture of low cost perovskite solar cells. To manufacture perovskite solar cells at low cost and at scale using slot-die coating it is essential to develop coating inks that reliably give high quality films under ambient conditions using fast and low temperature processes. Consideration must also be made for the suitability of the ink for use in an industrial setting so the toxicity and environmental impact of the ink must be minimised. The development and choice of various layers in the device stack will be explained and the results of using these to make perovskite solar cells with four layers slot-die coated presented. Optimisation of the coating and drying conditions will also be explained as well as the use of slot-die coating for the production of modules. Finally the transition from sheet based to reel-to-reel coating will be presented.
