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

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

    Abstract : 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. READ MORE

  4. 2. Epitaxial III-V/Si heterojunctions for photonic devices

    Author : Giriprasanth Omanakuttan; Sebastian Lourdudoss; Yanting Sun; Harri Lipsanen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epitaxy; heterojunction; III-V on Si integration; solar cell; Fysik; Physics;

    Abstract : Monolithic integration of III-V materials on silicon is of great interest for efficient electronic-photonic integrated devices and multijunction solar cells on silicon. However, defect formation in the heteroepitaxial layers due to lattice mismatch, thermal mismatch, and polarity mismatch makes it a great challenge. READ MORE

  5. 3. Surface Energy Patterning and Optoelectronic Devices Based on Conjugated Polymers

    Author : Xiangjun Wang; Olle Inganäs; Henning Sirringhaus; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface energy modification; Patterning; Dewetting; Conjugated polymer; plastic solar cell; Low bandgap; Electron acceptors and donors; Physics; Fysik;

    Abstract : The work presented in this thesis concerns surface energy modification and patterning of the surfaces of conjugated polymers. Goniometry and Wilhelmy Balance techniques were used to evaluate the surface energy or wettability of a polymer’s surface; infrared reflectionabsorption spectroscopy (IRAS) was used to analyse the residuals on the surface as modified by a bare elastomeric stamp poly(dimethylsiloxane) (PDMS).
