Abstract: The present invention provides a method for depositing an organic-inorganic perovskite, the method comprising the step of depositing a perovskite precursor solution comprising one or more organic cation, wherein said precursor solution preferably deposited by inkjet printing. The method is particularly useful in the manufacture of perovskite solar cells. For depositing the perovskite, a perovskite precursor solution or ink is preferably used, which comprises an organic cation carrying an anchoring group, such as 5-ammonium valeric acid. Surprisingly, the presence of the latter compound renders the precursor solutions stable and suitable for inkjet printing.

Abstract: The present invention concerns a method for deposition layers of an electronic device by slot-die deposition. Preferably, the method comprises slot-die deposition of formulation for providing compact inorganic layers, mesoporous inorganic layers, a carbon layer and a layer comprising organic-inorganic perovskite. In a preferred embodiment, the layers of a monolithic perovskite solar cell are entirely deposited by slot-die deposition. The method renders the manufacturing process of such electronic devices more efficient.
