| 内容記述 | Recently, perovskite solar cells （PSCs） have got much attention due to their high efficiency and low-cost fabrication. Within the last ten years, they have shown a sharp rise in efficiency from an initial 3.8% to over 25.5% thus enabling them the most promising upcoming new generation solar cells. However, the bottom neck of PSCs lies in the prospect of commercialization, such as industry-standard stability and further reduction of manufacturing cost. Nevertheless, the perovskite film quality has a great influence on the working stability of the PSCs. Therefore, in this thesis, we focus to enhance the stability of perovskite-based devices by controlling the morphology and utilizing the interface passivation strategy. In addition, the toxic of lead is also a main problem of perovskite solar cells. The main research contents are as follows: In chapter 1, the development history of photovoltaic technology and the classification of solar cells have been introduced. In addition, the structure, working principle and the development of PSCs also been described, Moreover, lead-free solar cells and Ag-Bi-I ruddorfite solar cells also have presented. At the same time, the current challenges and the purpose of this thesis have been described. In chapter 2, we describe the fabrication of a carbon-based CsPbI2Br PSC. An Imidazolium-based ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate （BMIMBF4）, was added to the CsPbI2Br perovskite film. The perovskite crystal quality and the device performance were improved. The results of SEM and XRD show that the additive of the ionic liquid can affect the perovskite nucleation and result in larger grain size. Furthermore, we also found that the addition of BMIMBF4 can reduce the energy barrier between the perovskite layer and carbon back electrode, which leads to better performance of PSCs. In chapter 3, in order to reduce the charge recombination, a simple surface passivation method with BMIMBF4 of CsPbI2Br was developed. The ionic liquid of BMIMBF4 as a modification layer can efficiently reduce the trap densities and inhibit non-radiative charge recombination, which made the efficiency up to 14%. We also observed that BMIMBF4 passivation can stabilize the CsPbI2Br phase at room temperature. In chapter 4, in order to explore non-toxicity and stable light-absorbing materials, we developed a Cs-incorporated AgBiI4 absorber, and the performance of this kind of rudorffite solar cells was improved due to the reducing trap-state density of AgBiI4 films and the efficient carrier transport. The Cs ion cooperated AgBiI4 exhibited an improvement of 40% in efficiency and better long-term stability than without Cs ion cooperation. In chapter 5, the conclusions and prospects are presented. Perovskite solar cells are facing significant challenges in terms of long-term stability and production costs. It would have great significance to further study the preparation of PSCs in the air environment. | |||||||
