Amélioration de l'absorption photonique dans les cellules photovoltaïques organiques

Abstract : The photovoltaic conversion efficiency of organic solar cells is still too low to start their production at industrial level. In this work, we present a method to enhance photon absorption in photoactive layers. The first part of this work is focused on the development of a software for modelize and optimize organic solar cells. Based on repartition of the electromagnetic field in depth of cells, this software allows layers thicknesses optimization of "single" solar cells or multijunction solar cells like tandem cell. In the second part, we compute short circuit current densities which allows to link optical properties to electrical properties of organic solar cells. Our calculus were then validated by comparison with bilayer heterojunction ( CuPc/C60) or bulk heterojonction(P3HT:PCBM, pentacene:perylene) solar cells. In the last part of this work we started a study concerning surface plasmon effects in organic layers. For that, we modelized, realized and characterized organic layers, including metallic nanoparticles (gold or silver), in order to enhance the localized electromagnetic field in these layers.
