Abstract

National audience; In the past years the application of ZnO in the domain of solar energy conversion has stimulated intensive research due to its possible application as transparent conducting oxide electrodes or an index matching layer to control the reflectivity of photovoltaic cells. ZnO is more attractive than usually used TiO2, as for a similar value of the bandgap, it exhibits higher electron mobility. A more unusual application of the ZnO nanostructures is to use it as the energy down-shifting material placed on the front side of a solar cell, to enhance the efficiency of the photovoltaic device, especially in the near UV spectral range. The key issue is to increase dramatically the ZnO nanostructure visible luminescence, which is necessary for an efficient down-shifting process, with respect to the ZnO excitonic emission at 3.37 eV. Even if a significant visible luminescence mainly related to the presence of crystalline defects (such as oxygen vacancies) can be easily observed in most of the ZnO nanoparticles (NPs) and nanowires, the precise control of the amount of this visible emission and full understanding of its origins still occurs to be a uneasy task.The ZnO NPs were fabricated using a purely physical method: the Low Energy Cluster Beam Deposition (LECBD). The nanoparticle size, stoichiometry, crystallinity and surface quality can be precisely controlled via the adjustment of the synthesis parameters (the partial pressure of the oxygen in the deposition chamber, the geometry of this chamber, the temperature of the substrate, etc.). Furthermore, the morphology, structure, crystalline size, composition and the stoichiometry of the fabricated NPs were characterized using the transmission electron microscopy, X-ray diffraction and Rutherford Backscattering Spectrometry.The light emission and the energy down-shifting properties of the fabricated NPs were studied using the photoluminescence (PL) technique, under the 244 nm UV laser excitation. In non-stoichiometric ZnO NPs a remarkable increase of the visible PL emission can be observed when excited with the UV laser and this enhancement occurs to the detriment of the NPs excitonic emission. The visible light emission is attributed to the presence of the oxygen defects in the NPs’ crystalline structure and we demonstrate that the emission characteristics of the fabricated NPs (and more precisely the ratio between the excitonic and the visible PL band) can be tuned via the control of the oxygen pressure in the deposition chamber during the deposition of the ZnO NPs by the LECBD technique. To characterize the influence of the defects on the visible PL of the ZnO NPs, we studied the room temperature PL properties of the ZnO NPs synthesized under various oxygen pressures in the deposition chamber. It is clearly demonstrated that there exists an optimal value of the oxygen pressure introduced during the LECBD process, which permits to obtain the highest visible PL emission from the ZnO NPs, necessary for the efficient down-shifting. The results of the ZnO NPs integration as a down-shifting layer into the structure of a monocrystalline silicon solar cell are also presented.
