Texto completo da fonteHalide perovskites have emerged as a promising new class of semiconductor materials for photovoltaic and optoelectronic applications. They present remarkable optoelectronic properties such as long carrier lifetime and diffusion length despite a high defect density. However, the underlying physical origin of the defect tolerance of HPs is still debated. A better understanding of the nature and impact of defects is still required in order to optimize further the devices. Additionally, with a strong spin orbit coupling, HPs are also promising for applications in spintronics. The investigation of the spin properties of HPs is just beginning. Solution-grown single crystals are to date the best system to explore the intrinsic properties of HPs.In this PhD, we investigate the optical and spin properties of single crystals of the archetypal 3D perovskite, CH3NH3PbI3. In a first part, we study the defect emission of CH3NH3PbI3 based on low temperature photoluminescence microscopy and spectroscopy. The excitation power dependence, time dynamics and temperature evolution of the defect emission is analysed. Series of sharp DAP lines with sub-meV width, the fingerprint of discrete DAP transition, are in particular observed.In a second part, PL excitation spectroscopy is used to study the relaxation pathway of carriers and excitons in CH3NH3PbI3 single crystals. The intrinsic free excitonic transition is only weakly involved in the relaxation toward the defect emission, and with no apparent contribution to DAP emission at low energy. In contrast, the results reveal the existence of a very efficient excitation of the DAP transition with below the band gap excitation at 1.633 eV. A strong enhancement of the defect emission is reported for both the broad band emission and the sharp luminescence lines. An excitation mechanism is proposed based on a bound-to-free transition. Then, the polarization of the sharp defect lines is studied and shows the existence of a significant degree of linear polarization of approximately 40% for several lines. The polarization of the defect lines can be interpreted as the indication of a preferential orientation of the DAP dipoles.In a third part, we shows that spectral diffusion can be observed in the sharp line emission of CH3NH3PbI3. The absence of antibunching indicates that the SD is not associated with single photon emission. The analysis of correlations in the SD of groups of PL lines shows that an ensemble of independent defects can experience the same fluctuations.Finally, we investigate the spin properties of CH3NH3PbI3. An optical set-up has been developed to control the polarization of light in both excitation and collection. In the absence of magnetic field, we measure two nearly orthogonal linearly polarized emission which can be associated to the bright excitonic states. An important degree of field-induced circular polarization of 50% is evidenced. Optical orientation under CW excitation lead to a degree of circular polarization of 55%. These results allow us to estimate the spin relaxation time to approximately 300 ps in CH3NH3PbI3 single crystals

Texto completo da fonteDue to instability problems of dye sensitized solar cells (DSSCs) in longtime uses, the iodine based liquidelectrolyte has been replaced by several types of solid hole transporting materials (HTM) to perform solidstate DSSCs (s-DSSCs). Among them, the substitution by conducting polymers (CP) has attractedconsiderable attention because of their good stability, high hole-conductivity and simple deposition withinthe mesoporous TiO2 semiconductor. In this thesis work, several s-DSSCs based on CPs used as HTM havebeen developed in order to improve their photovoltaic performances taking into account the following twoobjectives: (i) the optimization of the interfacial charge transfer processes within the solar cell, and (ii) theoptimization of the charge transport within the n-type oxide semiconductor. To reach these goals, eachcomponent that constitutes the device was varied in order to investigate its effect on the device’sperformances. As first attempt, an analytical study is carried out by varying the sensitizer in order todetermine the fragments of the dyes structures, that have an important effect on the in-situ photoelectrochemical polymerization process (PEP) both in organic and in aqueous media and hence on theperformances of the s-DSSCs. Based on these results, a new concept of removing completely the interfacebetween the dye and the HTM is developed. This is achieved by the synthesis of new dyes covalently linkedto an electroactive monomer which is co-polymerized by in-situ PEP. The resulting co-polymer, used asHTM, is covalently linked to the dye. In addition, the nature of the chemical bond linking the triphenylamineresidue TPA to the monomer is also investigated as a key factor in the s-DSSCs performances. Besides, andto optimize the charge transport processes within this type of s-DSSC, the elaboration of novel ZnO baseds-DSSCs has been achieved and investigated
