제목 The impact of controlled side chains on the morphology, molecular orientation of small molecule based photovoltaic devices.  
초록 A series of bis-benzodithiophene with different alkyl side-chain on thienyl group is synthesized for application as a photoactive material and hole transport layer in high-performance organic photovoltaics and perovskite solar cells. The designed small molecules provide totally different properties such as not only the optoelectronic, electrochemical and physical properties but also molecular packing/ordering and orientation. Surprisingly, when replacing alkyl side-chain, the well-ordered structure, high/balanced charge carrier mobility and favorable nanomorphology with preferable face‐on orientation are developed, which are beneficial for charge transfer, transport and recombination properties in photovoltaic cells.
