摘　　要：碳基钙钛矿太阳能电池(C-PSCs)具有稳定性好且成本低的优势,展现出广阔的应用前景。本研究基于MAPbI3材料,选择高质量的NiO_(x)介孔层作为空穴传输层(HTL),对比了NiO_(x)介孔层不同制备方法对电池性能的影响,并对NiO_(x)介孔层的厚度进行优化。研究发现,与旋涂工艺制备的NiO_(x)介孔层相比,丝网印刷工艺制备的介孔层的孔径分布均匀,可改善钙钛矿(PVK)前体溶液填充在介孔支架中的填充状态。最终得到含HTL的高效率和低滞后的钙钛矿太阳能电池,其开路电压(VOC)为910 mV,光电转换效率(PCE)为14.63%,认证效率达14.88%。此外,在空气中储存近900 h,其PCE没有明显衰减。Carbon-based perovskite solar cells(C-PSCs)play an important role in industrialization research due to their stability and low cost.In this work,high-quality NiO_(x) mesoporous layer was selected as a hole transport layer(HTL)based on MAPbI3 material to enhance the performance of C-PSCs.The effect of preparation methods of the NiO_(x) mesoporous layer on the solar cell performance and the optimum thickness of the NiO_(x) mesoporous layer were investigated.It was found that mesoporous layers prepared by screen-printing process with well-distributed pores facilitated the filling of perovskite(PVK)precursor solution in the underlayer mesoporous scaffold.Finally,an HTL-contained perovskite solar cell with high efficiency and almost negligible hysteresis was achieved,possessing an open-circuit voltage(VOC)of 910 mV,a power conversion efficiency(PCE)of 14.63%,and certified efficiency reached 14.88%.Moreover,PCE of the solar cell displayed outstanding stability after being stored in air for nearly 900 h.
