A great advantage of conjugated polymers is their solution processability with low cost. Conjugated polymers typically have flexible alkyl side chains for solubility in organic solvents, and J. Liu, L. Wang, and co‐workers report in their Communication on page 10376 ff. soluble conjugated polymers bearing novel side chains, branched oligo(ethylene glycol). These polymers can be used in solution‐processed polymer solar cells with high efficiency and near‐IR response.
