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NiOx介孔层作为空穴传输层(HTL), 对比了NiOx介孔层不同制备方法对电池性能的影响, 并对NiOx介孔层的厚度进行优化。研究发现, 与旋涂工艺制备的NiOx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。

Abstract:

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 NiOx 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 NiOx mesoporous layer on the solar cell performance and the optimum thickness of the NiOx 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.

Key words: carbon-based perovskite solar cell, NiOx hole transport layer, pore distribution, stability
