Abstract

See full text

An aspect of the present disclosure is a device that includes a first layer that includes a hole-transport material and an acid, where the first layer has a conductivity between 20 μS/cm and 500 μS/cm. In some embodiments of the present disclosure, the first layer may absorb light having a wavelength between 400 nm and 600 nm. In some embodiments of the present disclosure, the hole-transport material may include at least one of 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD), a derivative of spiro-OMeTAD, poly(triarylamine), poly(3-hexylthiophene), and/or N,N′-bis(3-methylphenyl)-N,N′-diphenylbenzidine.
