Instant p-doping and pore elimination of the spiro-OMeTAD hole-transport layer in perovskite solar cells

Chem Commun (Camb). 2024 Mar 26. doi: 10.1039/d4cc00111g. Online ahead of print.ABSTRACTAn 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.PMID:38530742 | DOI:10.1039/d4cc00111g
