INTERNATIONAL COOPERATIVE PROGRAMME FOR PHOTOVOLTAIC KESTERITE BASED TECHNOLOGIES (PVICOKEST)
Date du début: 1 mars 2011, Date de fin: 28 févr. 2015 PROJET  TERMINÉ 

The key objective of this multidisciplinary project is to intensify and consolidate cooperation between research groups from member states and Third countries on topics of synergy in research, innovation, sharing common expertise and technology transfer in the area of photovoltaic, more specifically in Kesterite materials. This project will provide the possibility to the involved research organizations, to reinforce their research cooperation on the long term. They will establish through this joint program, new opportunities for a further exploration of solar cell materials science, which plays nowadays a critical role in the implementation of technologies into area of photovoltaic devices. In this sense, the project aims to investigate absorber materials for thin film solar cells that only contain abundant and non-toxic elements as a contribution to a sustainable energy economy. Currently, earth-abundant copper-zinc-tin-chalcogenide kesterites Cu2ZnSn(Se,S)4, are potential alternatives for the two leading technologies Cu(In,Ga)(S,Se) (CIGS) and CdTe, reaching promising efficiencies over 9.6% . The obtained knowledge of these materials will help to understand their physics and give routes to engineer technologies of growing of structural perfect crystals, films and devices on their base. There is still a large need for an ample scientific study in order to support a future implementation of kesterites in the European industry. This multidisciplinary project comprises research activities in materials science and physics and includes the structural, optical and transport characterization of kesterite films and crystals. Throughout the exchange program the individual expertise available at the partners will be combined to study kesterites that are especially appropriate for use as materials for high-efficient, ecologically lovely and low-cost photovoltaic devices. Finally all ideas/developments will be turned into one device that will find applications in photovoltaics
