  1. 1. Thermoelectric plastics: Structure-property relationships of P3HT

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Jonna Hynynen; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; P3HT; structure-property relationships; F4TCNQ; vapor doping; Thermoelectric plastic;

    Abstract : The advancing development of inter-connected small devices, so-called Internet of Things is increasing the demand for independent power sources. Heat is an abundant and often wasted source of energy, thermoelectric generators could be used to harvest this waste energy. Small devices such as heart-rate monitors or gas sensors etc. READ MORE

  3. 3. Hole Transport Materials for Solid-State Mesoscopic Solar Cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lei Yang; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mesoscopic solar cells; solid-state dye-sensitized solar cells; organometallic halide perovskite; hole transport materials; mesoporous TiO2; conjugated polymer; sensitizer; transient absorption spectroscopy; photo-induced absorption spectroscopy; in-situ photoelectrochemical polymerization; spiro-OMeTAD; P3HT; TPAA; MeO-TPD; bis-EDOT; DEH; Li ion migration; charge recombination; electron lifetime;

    Abstract : The solid-state mesoscopic solar cells (sMSCs) have been developed as a promising alternative technology to the conventional photovoltaics. However, the device performance suffers from the low hole-mobilities and the incomplete pore filling of the hole transport materials (HTMs) into the mesoporous electrodes. READ MORE
