Discovery of novel semiconducting materials is needed for solar energy conversion and other optoelectronic applications. However, emerging low‐dimensional solar absorbers often have unconventional crystal structures and unusual combinations of optical absorption and electrical transport properties, which considerably slows down the research and development progress. Here, the effect of stronger absorption and weaker carrier collection of 2D‐like absorber materials are studied using a high‐throughput combinatorial experimental approach, complemented by advanced characterization and computations. It is found that the photoexcited charge carrier collection in CuSbSe 2 solar cells is enhanced by drift in an electric field, addressing a different absorption/collection balance. The resulting drift solar cells efficiency is <5% due to inherent J SC / V OC trade‐off, suggesting that improved carrier diffusion and better contacts are needed to further increase the CuSbSe 2 performance. This study also illustrates the advantages of high‐throughput experimental methods for fast optimization of the optoelectronic devices based on emerging low‐dimensional semiconductor materials.
