  2. 1. Sputtering-based processes for thin film chalcogenide solar cells on steel substrates

    Author : Patrice Bras; Charlotte Platzer-Björkman; Eric Jaremalm; Jan Sterner; Veronica Bernudez; Uppsala universitet; []
    Keywords : CIGS; CZTS; solar cell; photovoltaics; thin film; sputtering; annealing; gallium grading; blister; uniformity; stainless steel; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : Thin film chalcogenide solar cells are promising photovoltaic technologies. Cu(In,Ga)Se2 (CIGS)-based devices are already produced at industrial scale and record laboratory efficiency surpasses 22 %. Cu2ZnSn(S,Se)4 (CZTS) is an alternative material that is based on earth-abundant elements. READ MORE

  4. 2. Nanoparticle plasmonics for solar cell applications

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

    Abstract : 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. READ MORE
