合成了一种简单的咔唑基共轭烯胺V950，并对其进行了充分表征，并将其应用于钙钛矿太阳能电池中，其功率转换效率接近18%。所研究的空穴转运材料通过极其简单的路线（一步合成，没有昂贵的催化剂，没有柱层析或升华纯化），由市售和相对便宜的起始试剂合成，与市售的2,2',7,7'-四（N， N-二对甲氧基苯胺）-9-9'-螺双芴（螺- ometad）相比，最终产品的成本降低了一个数量级以上。这种材料有望成为一种可行的p型有机电荷导体，用于钙钛矿太阳能组件的扩大和制造。
A simple carbazole-based conjugated enamine V950 was synthesized, fully characterized and incorporated into a perovskite solar cell, which displayed high power conversion efficiency close to 18%. The investigated hole transporting material was synthesized via an extremely simple route (one step, no expensive catalysts, no column chromatography or sublimation purification) from commercially available and relatively inexpensive starting reagents, resulting in more than one order of magnitude lower cost of the final product compared to the commercial 2,2', 7,7'-tetrakis( N, N-di-p-methoxy-phenylamine)-9-9'-spirobifluorene (spiro-OMeTAD). This material promises to be a viable p-type organic charge conductor to be employed in the scale-up and manufacturing of perovskite solar modules.
