  1. Effect of Polymer–Fullerene Interaction on the Dielectric Properties of the Blend

    The relationship between the dielectric constant and the device performance is investigated in polymer solar cells. The increase in the dielectric constant observed upon polymer–fullerene blending correlates well with device performance, in contrast to the pristine polymer dielectric constant. More importantly, the increase in excited state polarizability upon blending is a key indicator of device performance and is responsible for efficient charge transfer.

  2. Hybrid Composite Coatings for Durable and Efficient Solar Hydrogen Generation under Diverse Operating Conditions

    A novel composite coating enables stable and efficient solar hydrogen generation under both basic and alkaline conditions and provides a versatile approach to scalably protect semiconductor light absorbers, integrate catalysts, and manage charge transport. This strategy is verified by demonstration of devices with unbiased solar-to-hydrogen conversion efficiencies exceeding 10% with pure gas product streams in both laboratory and outdoor testing environments.

  3. Charge Transfer from Methylammonium Lead Iodide Perovskite to Organic Transport Materials: Efficiencies, Transfer Rates, and Interfacial Recombination

    The dynamics of charge transfer from CH3NH3PbI3 to charge-specific transport materials are revealed using time-resolved microwave conductivity measurements and a global kinetic model. Hence, the authors find that the transfer rates to C60, PCBM, EDOT-OMeTPA, and Spiro-OMeTAD are sufficient to outcompete other recombination pathways at excitation densities representative for AM1.5, while this is not the case for bis-PCBM, ICBA, and H101.

    To simultaneously collect two or more types of water energy still remains challenging for the freestanding model of triboelectric nanogenerator (TENG). In this work, multifunctional TENG is developed that not only can successfully be used to simultaneously harvest water waves, air flowing, and water flowing based on the freestanding model, but also can be explored as a self-powered speed sensor of wind.

    Ternary polymer solar cells based on PTB7-Th:PffBT4T-2OD:PC71BM are designed according to the complementary properties of PTB7-Th and PffBT4T-2OD. The highest efficiency of 10.72% for this ternary system is achieved with 15% PffBT4T-2OD. As for the working mechanism, this ternary system paves the way to investigate the morphology–performance relationship. Moreover, the energy transfer is involved in ternary blend.
