Process for the production of thin layers, preferably for a photovoltaic cell

The invention is directed to a process for the production of a thin layer, preferably for a photovoltaic cell, which cell has at least a first contact layer, a p-type semiconductor layer, an n-type semiconductor layer, or a combined p-type/n-type semiconductor layer, and a second contact layer, said process comprising applying the layer or the various layers on top of each other, wherein at least one of the layers is applied using pulsed spraying of a solution of precursor material for the layer.
