The development of sustainable energy has become a critical issue nowadays as the situation of global warming gets worsened. In this regard, solar energy has attracted tremendous research interests in the past decade. Among the exploited solar energy techniques thus far, organic photovoltaics (OPVs) have attracted particular attention due to their excellent mechanical flexibility, light-weight, and low-cost properties, which has been considered as potential candidates to fulfill the development of soft electronics. However, besides the advances in controlled synthesis of organic semiconductors, innovative interfacial and device engineering on bulk-heterojunction devices are also critical for achieving high-performance OPVs. The performance is strongly dependent on their efficiency in harvesting light, exciton dissociation, charge transport, and charge collection at the metal/organic/metal oxide interfaces. In this presentation, an integrated study of combining interface, optical, and device engineering will be first introduced and discussed to explore the full promise of OPVs. Afterward, we further translate the knowledge accumulated in OPVs into the emerging organic-inorganic hybrid perovskite solar cells (PVSCs) to develop stable and high-performance devices. |
