With the capability to manipulate the built‐in field in solar cells, ferroelectricity is found to be a promising attribute for harvesting solar energy in solar cell devices by influencing associated device parameters. Researchers have devoted themselves to the exploration of ferroelectric materials that simultaneously possess strong light absorption and good electric transport properties for a long...
Ternary blend organic solar cells (OSCs) composed of three components in the active layer shows the potential to achieve higher power conversion efficiency (PCE) as compared to the binary counterpart due to the wider absorption spectrum, higher generation rate, and better morphology. However, the physical understanding of carrier generation and transport processes in the ternary blend OSCs has been...
We investigate both optical and electrical properties of organic photovoltaics (OPVs) by a comprehensive multiphysics model.Using a unified finite-difference approach, the multiphysics model for OPVs is established for seamlessly connecting photon absorption to the exciton delocalization and diffusion, and to carrier transport and collection. Here we solve the Maxwell's equations and semiconductor...
Due to the advantages of low cost, easy fabrication, mechanical flexibility, the research on organic solar cells has attracted a lot of attentions in the last decades. Among countless organic materials, the most successful ones are conjugated polymers, which were widely used in bulk heterojunction (BHJ) in conjugation with the fullerene [1]. In view of the fact the interpenetratedphase-separated p-n...
