Rezumat

Among the most interesting renewable energies, solar energy is very well suited to respond to the increasing necessities of the humanity. Solar light constitutes an inexhaustible energy source: the Earth receives from the sun in one hour and a half, the energy to cover the humanity needs during one year; evidencing the importance of the development of this source of energy. But the future deployment of the photovoltaic technology is compromised by both, the development of costeffective processes as well as the use of earth abundant and low toxic materials, without scarifying the devices efficiency. In this framework, enormous efforts have been done in the last years for the development of chemical based routes applied to the mass production of thin film photovoltaic technologies, which are in turns less expensive than classical vapour phase ones, but that generally lead to lower efficiency devices. Additionally, two of the most mature technologies in the thin films photovoltaic field (CdTe and Cu(In,Ga)Se2 (CIGS)) have the problem of the scarcity and/or high toxicity of some of their constituent elements, claiming for their future replacement by earth abundant and less toxic materials. In this presentation, a review of the last advances on the low-cost thin films photovoltaic technologies will be presented, focusing on the discussion of the key advantages and drawbacks of the chemical/electrochemical routes, and their future challenges and perspectives to replace more expensive vapour phase based techniques. In particular, the presentation will be focused on the last results obtained in cost-effective techniques like: electroplating, spray pyrolisis and ink-printing. In addition, new earth abundant and low toxicity chalcogenides, based on kesterite compounds as Cu2ZnSn(S,Se)4 (CZTS) will be presented. These compounds are today the best suited materials to answer to the increasing demand of solar energy. Last results obtained in the preparation and characterization of CZTS based solar cells in the Advanced Materials for Energy Department of IREC will be also presented.
