| Abstract |
Over the past few decades, polymer solar cells (PSCs) have made a significant progress, showing their potential in low-cost, flexible, lightweight, portable and large-area energy-harvesting devices. Considerable efforts have been dedicated toward the design of new materials, device architectures and processing techniques in order to improve the power conversion efficiency (PCE). To further improve the PCE value, first and foremost, the molecular structures of p- and n-type photovoltaic materials should be carefully designed by considering its close relationship with the photovoltaic parameters, including short-circuit current density (Jsc), open-circuit voltage (Voc) and fill factor (FF). Here, we present a series of crystalline photovoltaic conjugated molecules which were designed by considering the backbone planarity, noncovalent intra- and interchain interactions (via H-bonding and dipole-dipole interactions, etc) and solution processibility, leading to highly ordered film morphologies and PCEs approaching ~10%. The molecular design and resulting morphological, electrical and device properties will be discussed in detail. |
