  2. 11. Interfacial Analysis and Charge Transfer in Solar Cells

    Author : Xinjian Geng; Jacinto Sá; Ellen Moons; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perovskites; Charge Transport Layer; Plasmonics; Hot Carriers; Interfaces; Photoluminescence; Solar Cells; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : Harnessing sunlight through solar cells is vital for sustainable energy production. The conventional architecture of a solar cell consists of multilayers of materials, each serving a particular function. The absorbing layer converts the solar energy into valuable electricity by the photovoltaic effect. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photovoltaic cells; parabolic reflectors; optical efficiency; Solar concentrators; photovoltaic-thermal systems; non-imaging optics; optical properties; building integrated photovoltaics; non uniform irradiance distribution; structured reflectors; solar cell modelling; ray tracing;

    Abstract : Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. READ MORE

  5. 13. Ionic Liquid Electrolytes for Photoelectrochemical Solar Cells

    Author : Heléne Gamstedt; Lars A. Kloo; Michael Grätzel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquid electrolytes; Photoelectrochemical solar cells; Inorganic chemistry; Oorganisk kemi;

    Abstract : Potential electrolytes for dye-sensitized photoelectrochemical solar cells have been synthesized and their applicability has been investigated. Different experimental techniques were used in order to characterize the synthesized electrolytes, such as elemental analysis, electrospray ionisation/mass spectrometry, cyclic voltammetry, dynamic viscosity measurements, as well as impedance, Raman and NMR spectroscopy.

    Abstract : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. READ MORE

  7. 15. Hole Transport Materials for Solid-State Mesoscopic Solar Cells

    Author : Lei Yang; Anders Hagfeldt; Erik Johansson; Gerrit Boschloo; Fengling Zhang; Uppsala universitet; []
    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
