  2. 1. Optical modelling of conjugated polymers : from materials to devices

    Author : Nils-Krister Persson; Andy Monkman; Linköpings universitet; []
    Keywords : Spectroscopic ellipsomctry; optical modelling; organic solar cell; conjugated polymer; polyfluorene; polythiophene; copolymer; fullerene blend; photovoltaic device; dielectric function; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Measurements and modelling of theoretical properties of polymer-based photovoltaic devices, PPVDs, are the subjects of this thesis. Modelling refers both to modelling of materials, based on extraction of the dielectric function, and to modelling of devices by computer simulation of the optical electrical field inside PPVDs.

  4. 2. Kinetic Monte Carlo Modelling of Organic Photovoltaic Devices

    Author : Tanvi Upreti; Martijn Kemerink; Feng Gao; Tayebeh Ameri; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Organic photovoltaics (OPVs) is a rapidly growing low-cost PV technology sector that relies on multiple benefits of organic semiconductors viz. being environmental-friendly with a simplified processing/fabrication and tunable properties. READ MORE

  5. 3. Polymer/polymer blends in organic photovoltaic and photodiode devices

    Author : Yuxin Xia; Olle Inganäs; Ergang Wang; Hin-Lap Yip; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Organic photovoltaics devices (OPV) have attracted attentions of scientist for their potential as inexpensive, lightweight, flexible and suitable for roll-to-roll production. In recent years, considerable attention has been focused on new acceptor materials, either polymeric or small molecules, to replace the once dominating fullerene derivatives. READ MORE

  6. 4. Light Trapping and Alternative Electrodes for Organic Photovoltaic Devices

    Author : Kristofer Tvingstedt; Olle Inganäs; Peter Peumans; Linköpings universitet; []
    Keywords : Light trapping; Organic solar cells; Tandem cells; Polymer solar cells; Plastsolceller; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Organic materials, such as conjugated polymers, have emerged as a promising alternative for the production of inexpensive and flexible photovoltaic cells. As conjugated polymers are soluble, liquid based printing techniques enable production on large scale to a price much lower than that for inorganic based solar cells. READ MORE

  7. 5. Hot-carrier extraction in nanowires

    Author : Jonatan Fast; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Hot carrier; photovoltaic; Thermoelectric; Fysicumarkivet A:2023:Fast;

    Abstract : A hot-carrier solar cell aims to generate power from energetic, photoexcited, charge carriers, so called hot carriers, in order to reach higher conversion efficiencies than current solar cell technology.Creating a hot-carrier solar cell has proven challenging for two main reasons: hot carriers lose their energy very quickly, and they need to be extracted over distances of a few hundrednanometers via energy selective filters.
