Mixed ion perovskite solar cells (PSC) are manufactured with a metal-free hole contact based on press-transferred single-walled carbon nanotube (SWCNT) film infiltrated with 2,2,7,-7-tetrakis(N,N-di-p-methoxyphenylamine)-9,90-spirobifluorene (Spiro-OMeTAD). By means of maximum power point tracking, their stabilities are compared with those of standard PSCs employing spin-coated Spiro-OMeTAD and a thermally evaporated Au back contact, under full 1 sun illumination, at 60 °C, and in a N atmosphere. During the 140 h experiment, the solar cells with the Au electrode experience a dramatic, irreversible efficiency loss, rendering them effectively nonoperational, whereas the SWCNT-contacted devices show only a small linear efficiency loss with an extrapolated lifetime of 580 h.
杂化离子钙钛矿太阳能电池（PSC）采用基于无金属空穴接触的压印转移单壁碳纳米管（SWCNT）薄膜制造，该薄膜浸润有 2,2,7,7-四（N,N-二对甲氧基苯基胺）-9,90-螺二芴（Spiro-OMeTAD）。通过最大功率点跟踪，在 60°C 和 N 气氛下，在全 1 个太阳光照射下，将具有 Spiro-OMeTAD 和热蒸发 Au 背电极的标准 PSC 的稳定性与采用旋涂 Spiro-OMeTAD 和热蒸发 Au 背电极的标准 PSC 的稳定性进行了比较。在 140 小时的实验过程中，具有 Au 电极的太阳能电池经历了急剧的、不可逆的效率损失，使其实际上无法运行，而 SWCNT 接触器件仅表现出小的线性效率损失，其外推寿命为 580 小时。
