| 内容記述 | Perovskite solar cells （PSCs） have attracted much attention due to their feasible fabrication process, low cost and high efficiency.As one of the most promising photovoltaic devices, PSCs have achieved the power conversion efficiency （PCE） of 25.2% recently. However, the stability and toxic lead issues of perovskites still inhibit their large-scale applications. The perovskite will degrade in months under atmosphere, quite low than its counterpart like silicon solar cells of years. The large number of traps residing in perovskite interface account for the instability of perovskite, deterioration of PCE and leakage of the poisonous lead. In this thesis, we employed the interfacial passivation in the polycrystalline perovskite films for PSCs. In addition, Sb-based complexes with pyridyl cations were carried out and successfully implemented as an absorber layer for solar cell. As a result, the device with enhanced performance and superior stability was achieved, as well as replacing Pb to alleviate the toxic problem and enrich the perovskite family. In chapter 1, the background of photovoltaic materials and their currently development, including the properties perovskite semiconductors, and the fabrication of perovskite solar cells are introduced. The basic principle of perovskite solar cells and their photovoltaic performance measurements are depicted. Moreover, the issues of research in perovskite materials and motivation of this thesis are presented. In chapter 2, we presented a La-doped SnO2 electron transport layer （ETL） for the planar PSC. The performance of perovskite solar cell was improved due to the uniform coverage of La doped SnO2 ETL film. The conductivity and transparency of the SnO2 were also enhanced after the lanthanide doping, thus facilitated the charger injection and transfer of electrons. Furthermore, the upshift of the CBM reduces the band offset at the La-doped SnO2/perovskite interface, thus minimizing the energy loss leading to a Voc up to 1.11 V. This study revealed the advantages of lanthanide doping within the SnO2 layer, which is an important approach for improving the performance of PSCs with a low-temperature processed ETL fabrication. In chapter 3, an interfacial modification method was developed for improving the efficiency and stability of the inorganic perovskite solar cells. We found that the interfacial modification can stabilize the metastable CsPbIBr2 perovskite. The optimizing device maintained 90% of its initial PCE for 30 h and photoactive over 400 h in ambient air. The reduced trap defect in perovskite yielded the enhanced PCE of 9.33% with Voc of 1.33 V. In chapter 4, two kinds of lead-free absorbers were prepared via a simple solution-process method with high Voc and good stability solar cell devices. As lead-free absorbers, the development of these novel Sb-based perovskites showed potential application for photovoltaic devices. Finally, general conclusion and prospects are given for the solar cell’s application. Perovskite solar cells are still facing the significant challenges in terms of long-time stability and toxic of lead with environment concerns. The interfacial passivation is an effective method to obtain efficient and stable perovskite solar cell. In addition, the development lead-free perovskites can be helpful to solve the toxic lead problem for their commercialization. | |||||||||
