The project is focused on the development of indium-free organic (OPV) and hybrid photovoltaic (HPV) cell structures on flat and nanopatterned multilayer transparent conductive electrode (MTCE) on rigid and flexible substrates. Thus, the expensive indium tin oxide (ITO), the most used transparent conductive electrode in the OPV/HPV cell structures, will be replaced by low-cost MTCE based on metallic oxide/ metal/ metallic oxide (ZnO/Ag(Au)/ZnO) films with lower thickness than the classical single layer ITO but with similar properties to this. In addition, low quantity of material will be used (compared to the silicon based systems) to prepare the active films (organic/inorganic nanostructures in organic) of the OPV/HPV cells. The inorganic nanostructures based on copper sulphides will be inserted in the organic matrix for improving the optical and electrical properties of the developed structures and also to increase their stability.  Patterned surfaces obtained by UV nanoimprint lithography will be involved in order to increase efficiently the light harvesting in the active layers and in this way enhancing the electrical parameters of the fabricated PV cells. The fabricated OPV/HPV devices within this project can be further used in niche applications (ex. small electronic devices, wearable electronics, etc.).
