VIP: Non-Conjugated Polymer as an Efficient Dopant-Free Hole-Transporting Material for Perovskite Solar Cells

Non-Conjugated Polymer as an Efficient Dopant-Free Hole-Transporting Material for Perovskite Solar Cells

Be flexible: By integrating a flexible polyvinyl main chain with carbazole-based hole-transporting side chains, a new non-conjugated polymer (PVCz-OMeDAD) with excellent film-forming ability and good hole mobility is designed and synthesized in high yield through a three-step reaction. By employing the ultra-thin PVCz-OMeDAD film (≈30 nm) as dopant-free hole-transporting layer, perovskite solar cells (PSCs) can realize a power conversion efficiency up to 16.09 %, suggesting the great potential of this non-conjugated polymer for future low-cost, large-scale, flexible PSCs applications.

    Keep the TEMPO: Stable porous organic frameworks (POFs) with a built-in radical moiety (TEMPO) were prepared by a bottom-up strategy. These TEMPO-POFs were applied as host cathode materials for Li−S batteries with good cycling performance. Furthermore, TEMPO-POFs with sulfur embedded showed excellent rate capability with limited capacity loss at rates of 0.1–1 C.

    Interface activation: An easy but effective approach to generating a rich amount of oxygen vacancies (VO) in Co3O4 nanocrystal-based oxygen evolution reaction (OER) electrodes by constructing a highly coupled interface with metallic Ti is demonstrated. Oxygen vacancies help to capture water molecules for OER in neutral electrolyte, resulting in impressively high current density and TOF value at an OER overpotential of 570 mV.
