Solar Cells Small‐molecule organic solar cells (SMOSCs) have recently gained attention as sources of renewable energy owing to their advantages such as easier synthesis, less batch‐to‐batch variation, and better reproducibility with regard to performance as compared to polymer‐based solar cells. In their Full Paper on page 1045 ff. , highlighted on the Inside Cover, Yun‐Hi Kim et al. designed and synthesized two small molecules bearing a thieno[3,4‐ c ]pyrrole‐4,6‐dione (TPD) unit. These compounds show an excellent thermal stability, strong absorption, relatively low HOMO levels, and high hole mobility. SMOSCs based on blends of these donor molecules and a phenyl‐C 61 ‐butyric acid methyl ester acceptor display power conversion efficiencies as high as 4.6 %.
