Amélioration des performances des cellules solaires organique par l'ingénierie de bandes aux interfaces électrodes semi - conducteurs

Abstract : The current context of strong growth in energy demands in the world requires diversification of its production, in particular towards renewable sources while limiting as far as possible the emission of greenhouse gases. Among the most promising and abundant renewable energies is solar energy and it is evident that solar, thermal or photovoltaic energy represents a crucial issue to reduce the consumption of fossil energy. Currently 90% of the solar generators are made of crystalline silicon, which poses a problem of supply of raw material, as silicon producers did not know how to anticipate the strong expansion of the solar sector. Innovative concepts present a high potential in terms of cost of production and application, in particular organic and hybrid (organic / metal oxide) dies. In Europe, France is very active in this area of research, particularly with regard to the use of new organic nanostructured materials or hybrid structures. This is why Disasolar, a French start-up specializing in flexible photovoltaics, wants to develop this activity by developing flexible solar modules by inkjet printing. The objectives of this thesis are to study new printable interface materials and to evaluate the effect of nanoparticle size on the topology and performance of devices. And secondly, the study will focus on the printing of interface materials and the stability of organic solar cells.
