An instant p-doping strategy employing 4-tert-butyl-2-chloropyridine and tert-butyl peroxybenzoate for the spiro-OMeTAD hole-transport layer (HTL) in perovskite solar cells (PSCs) is proposed to replace the conventional 4-tert-butylpyridine-doped HTL. The novel doping process eliminates the formation of pores in the HTL. Meanwhile, a 21.4% efficiency is achieved on the corresponding absolute methylammonium-free PSCs with significantly improved thermal and moisture stability.

钙钛矿太阳能电池中spiro-OMeTAD空穴传输层的即时p掺杂和孔隙消除

提出了一种即时 p 掺杂策略，采用 4-叔丁基-2-氯吡啶和过苯甲酸叔丁酯用于钙钛矿太阳能电池（PSC）中的 spiro-OMeTAD 空穴传输层（HTL），以取代传统的 4-叔丁基丁基吡啶掺杂的 HTL。新颖的掺杂工艺消除了 HTL 中孔的形成。同时，相应的绝对不含甲基铵的 PSC 实现了 21.4% 的效率，并且热稳定性和湿度稳定性显着提高。
