  A high-performance p-type transparent conductor (TC) does not yet exist, but
could lead to advances in a wide range of optoelectronic applications and
enable new architectures for, e.g., next-generation photovoltaic (PV) devices.
High-throughput computational material screenings have been a promising
approach to filter databases and identify new p-type TC candidates, and some of
these predictions have been experimentally validated. However, most of these
predicted candidates do not have experimentally-achieved properties on par with
n-type TCs used in solar cells, and therefore have not yet been used in
commercial devices. Thus, there is still a significant divide between
transforming predictions into results that are actually achievable in the lab,
and an even greater lag in scaling predicted materials into functional devices.
In this perspective, we outline some of the major disconnects in this materials
discovery process -- from scaling computational predictions into synthesizable
crystals and thin films in the laboratory, to scaling lab-grown films into
real-world solar devices -- and share insights to inform future strategies for
TC discovery and design.
