英文摘要： The organometal trihalide perovskite as an emerging star material exhibit amazing leaping progress and huge application potential in the field of solar cells. In this project, the CH3NH3PbI3-xMx(M=Cl, Br) perovskite quantum dots sensitized ZnO nanowires arrays organic-inorganic hybrid all solid-state solar cells will be fabricated. By adjusting the doping concentration of chlorine or bromine in perovskite, the photovoltaic performance of solar cells will be systematically investigated and the relative mechanism of interfacial charge behaviors will be revealed. The detailed content includes the following parts: The perovskite quantum dots will be deposited in situ on the ZnO nanowires arrays with effective doping; According to the native structure and property of perovskite, the effects and its corresponding mechanism of chlorine or bromine doping on the structural, optical and electrical properties will be investigated in detail by both theoretical calculation and advanced experimental characterization; The relationship between chlorine or bromine doping and photovoltaic performance will be clarified by systematically investigating how the doping influences the photovoltaic performance of solar cells; The variation of interfacial charge behaviors via chlorine or bromine doping, such as generation, separation, transportation and recombination, will be systematically investigated and the relative mechanism will be revealed. All the results not only benefit for the thorough understanding of native mechanism of this type solar cell, but also provide necessary experimental basis and theoretical instruction for further improving their photovoltaic performance.
