  1. 1. Nanoparticle plasmonics for solar cell applications

    Författare :Viktoria Gusak; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; titanium dioxide.; Localized Surface Plasmon Resonance; mesoporous material; Plasmonic nanoparticle; amorphous hydrogenated Silicon; solar cell; Dye-Sensitized Solar Cell; diffusion;

    Sammanfattning : The energy demand of society increases rapidly, while the main source of today’s energy, the fossil fuels, eventually will be depleted and also poses environmental and climate hazards (though the global warming). Therefore there is a need for alternative, renewable energy sources, and solar photovoltaics (solar cells) will play an important role as one of them. LÄS MER

  3. 2. Photoelectrochemical studies of dye-sensitized solar cells using organic dyes

    Författare :Tannia Marinado; Anders Hagfeldt; Katoh Ryuzi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; additive; charge recombination; coadsorbent; conduction band shift; dye-sensitized; electron lifetime; electron-transfer; organic dye; photoelectrochemical; photovoltaic; sensitizer; semiconductor; solar cell; solar cell efficiency; titanium dioxide; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The dye-sensitized solar cell (DSC) is a promising efficient low-cost molecular photovoltaic device. One of the key components in DSCs is the dye, as it is responsible for the capture of sunlight. State-of-the-art DSC devices, based on ruthenium dyes, show record efficiencies of 10-12 %. LÄS MER

  4. 3. Combined Electrical Power Generation using Solar and Wind

    Författare :Ingemar Mathiasson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave length bands; atmospheric transmittance; energy storage; Wind turbine; wind speed; quantum dots; electrical load.; extinction coefficient; silicon solar cell; solar cell;

    Sammanfattning : The need for systems for renewable electrical power production is enormous worldwide.This applies to systems of varying size and capacity. From small systems for household purposes up to large systems for regional purposes. If possible, all systems should be linked in a common power grid. LÄS MER

  5. 4. Synthesis and Robotized Screening of Novel Perovskite Materials for Solar Cell Application

    Sammanfattning : As of today, the energy consumption in the world is high and is essential in the development and growth of the modern-day society. The world energy consumption is projected to increase significantly over the next decades. LÄS MER

  7. 5. Recycling of CIGS solar cell waste materials

    Författare :Anna Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrometallurgy; Pyrometallurgy; CIGS; Recycling; Solar cells;

    Sammanfattning : The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. LÄS MER
