  1. 21. Loss Mechanisms In Non-Fullerene Organic Solar Cells

    Författare :Huotian Zhang; Feng Gao; Olle Inganäs; Weimin Chen; Jenny Nelson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photovoltaics; organic solar cell; non-fullerene; charge recombination; voltage loss; fill factor;

    Sammanfattning : Photovoltaics are one of the most important sustainable energy sources in the 21st century. Among photovoltaics, organic solar cells (OSCs) offer many advantages such as ease of processing, lightweight, the potential for flexibility, and tunable properties. Its peculiar nature and complexity present a fascinating charm, attracting many researchers. LÄS MER

  4. 23. Ultralow-loss silicon nitride waveguides for nonlinear optics

    Författare :Zhichao Ye; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultralow loss; Kerr nonlinear optics; parametric amplifier; DKS microcombs; integrated waveguides; silicon nitride;

    Sammanfattning : The field of nonlinear optics relies on the interaction between high-intensity optical waves and nonlinear media. An integrated waveguide with large refractive index contrast allows to highly confine optical waves in a sub-μm^2 area, thus enhancing the optical intensity. LÄS MER
