The invention relates to a method for producing photoactive layers, and to components, such as solar cells, comprising said layers. According to the invention, the photoactive layers are produced by forming a non-semiconducting layer from precursor material comprising at least one metal compound and a salt-like and/or organic reactant on a substrate by printing or blade coating, said layer being exposed to temperatures of less than 300°C, wherein a semiconducting, photoactive layer is formed from the non-semiconducting layer by thermal conversion of the precursor material.
L'invention concerne un procédé de fabrication de couches photoactives et des composants, comme des cellules solaires, comprenant ces couches. Les couches photoactives sont fabriquées selon l'invention en appliquant sur un substrat une couche non semi-conductrice exposée à des températures inférieures à 300°C à partir d'un matériau précurseur comprenant au moins un composé métallique et un réactif salin et/ou organique par compression ou raclage, une couche photoactive semi-conductrice étant obtenue par conversion thermique du matériau précurseur à partir de la couche non semi-conductrice.
