Incorporation of a multifunctional liquid crystal (LQ) into (2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD)-based hole transport layer (HTL) of perovskite solar cells (PSCs) can strongly enhance hot carriers extraction/transfer from perovskite layer into HTL, reducing charge-carrier recombination in device. Moreover, LQ can efficiently prevent the Li ions migration and agglomeration of Lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) HTL dopant through chemical interaction. Using this approach, highly efficient and stable PSCs are achieved.

多功能液晶作为空穴传输层添加剂提高钙钛矿太阳能电池的效率和稳定性

将多功能液晶（LQ）纳入（2,2',7,7'-四（N,N-二-对甲氧基苯胺）-9,9'-螺二芴（Spiro-OMeTAD）基空穴传输层钙钛矿太阳能电池（PSC）的HTL可以强烈增强热载流子从钙钛矿层到HTL的提取/转移，减少器件中载流子的复合。此外，LQ可以有效防止锂离子的迁移和双（三氟甲磺酰基）锂的团聚通过化学相互作用作为酰亚胺（Li-TFSI）HTL掺杂剂，利用这种方法，可以获得高效且稳定的PSC。
