  1. 1. Organic Solar Cell Fabrication and Study on the Influence of Spin-dependent Processes on the Photocurrent using Spin-sensitive Techniques

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Ronja Olsmats Baumeister; Evelina Roxner; [2022]
    Keywords : EDMR; EPR; trEDMR; PEDOT:PSS; PCBM; P3HT; organic solar cells; osc; opv;

    Abstract : Research in recent years on novel materials in organic solar cells (OSCs) have contributed to a rapid advancement in OSC efficiency. Here, OSCs with the well-studied organic semiconductors poly(3-hexylthiophene):[6,6]-phenyl C60-butyric acid methylester (P3HT:PCBM) in a bulk heterojunction structure were prepared to establish a baseline procedure for fabrication and spin-sensitive spectroscopy.

  3. 2. Iron-Based Dye-Sensitized Solar Cells - From Theory to Working Solar Cell

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Linnea Lindh; [2019]
    Keywords : Dye-sensitized solar cells; Grätzel cells; solar cells of the future; solar cells of tomorrow; spectroscopy; time-resolved spectroscopy; materials chemistry; materialkemi; Chemistry;

    Abstract : In the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions.

  4. 3. Electrical and Optical Characterization of InAsP/InP Nanowire-Based Avalanche Photodetectors

    University essay from Högskolan i Halmstad/Fotonik

    Author : Praveen Kumar Singaravelu; Tawhidul Alam Mohammad; [2016]
    Keywords : ;

    Abstract : The availability of new manufacturing methodology in solid state physics makes it possible to grow nano-photonic devices for better performance and unique properties. In this thesis work, we use I-V and FTIR spectroscopy to study the electrical and optical properties of InAsP/InP nanowire-based array avalanche photodetectors for near infrared applications.

  5. 4. Identification of process induced defects affecting the performance of nanowire based solar cells by spatially resolved photocurrent measurements

    University essay from Lunds universitet/Fasta tillståndets fysik

    Author : Calvin Kan; [2013]
    Keywords : Nanowires; solar cells; nanotechnology; sustainable development; photocurrent measurements; energy; Technology and Engineering;

    Abstract : Solar power clearly has one of the greatest potential among renewable energy but a big setback is that it is still relatively expensive. Engineering of materials on a nanoscale, e.g. READ MORE

  6. 5. Organic-inorganic hybrid perovskites as light absorbing/hole conducting material in solar cells

    University essay from Fysikalisk kemi

    Author : Saman Ghanavi; [2013]
    Keywords : ;

    Abstract : Solar cells involving two different perovskites were manufactured and analyzed. The perovskites were (CH3NH3)PbI3 and (CH3NH3)SnI3. Both perovskites have a shared methyl ammonium group (MA) and are used as both light absorbing material and hole conducting material (HTM) in this project. READ MORE
