Abstract

Abstract : A novel robot‐based high‐throughput film‐fabrication technique, introduced by Loïc M. Roch, Thomas Heumueller, and co‐workers in article number 1907801, enables quaternary semiconductor blends to be fully screened for organic photovoltaic applications. This is realized by drop‐casting 96 individual solutions onto a pre‐structured glass plate, resulting in smooth and homogeneous layers. Moreover, the use of machine‐learning algorithms enables an autonomous operation toward highly efficient optimization routines, leading to a 30‐fold faster rate than conventional high‐throughput approaches.
