Record power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) have been obtained with the organic hole transporter 2,2',7,7'-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9'-spirobifluorene (spiro-OMeTAD). Conventional doping spiro-OMeTAD hygroscopic lithium salts and volatile 4-tert-butylpyridine is a time-consuming process also leads to poor device stability. We developed new strategy for that avoids post-oxidation by using stable radicals as dopant ionic modulator (referred...
Abstract Metal halide perovskites are emerging as promising semiconductors for cost-effective and high-performance light-emitting diodes (LEDs). Previous investigations have focused on the optimisation of emissive perovskite layer, example, through quantum confinement to enhance radiative recombination or defect passivation decrease non-radiative recombination. However, an in-depth understanding how buried charge transport layers affect crystallisation, though critical importance, is...
