摘要
太阳能有效转化为电能是满足日益增长的能源需求最理想的途径~([1])。基于甲胺基卤化铅(如CH_3NH_3PbI_3)的钙钛矿太阳能电池,由于其优异的光电转化效率与较低的制作成本等优势而受到了广泛关注~([2]),然而其稳定性问题仍亟待解决。考虑到聚乙烯咔唑具有良好的疏水性与成膜性能,我们将其引入钙钛矿层与空穴传输层之间,可有效隔绝环境中的水分并降低载流子复合率。同时,我们设计并合成了一系列三聚茚核心的空穴传输材料(SP-10~SP-12),该类分子具共轭的刚性平面结构和出色的空穴迁移率。在二者协同作用下,电池的光电转化效率达到了19.1%,且具有良好的稳定性。
Perovskite solar cells have drawn dramatically increased attentions due to their high power conversion efficiencies, easy fabrication, and low-cost. However, the long-term stability is the biggest remaining challenging issue. Herein, ultrathin poly(N-vinylcarbazole) films have been employed in PSCs as interlayer between perovskite layers and HTMs, which can simultaneously improve cell stability and suppress charge combination in PSCs. Moreover, a series of novel HTMs with truxene cores have been designed and synthesized, and a promising PCE of 19.1% has been achieved with poly(N-vinylcarbazole) as interlayer and SP-12 as HTM.
