  1. 1. Creation of thin film CuSbSe2 through closed space vapor transportdeposition

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Malin Eriksen; [2018]
    Keywords : CuSbSe; CuSbSe2;

    Abstract : With an increasing demand for fossil-free energy the development of efficient solar cells made from sustainable and abundant materials is needed. A promising group of new absorber materials are the chalcogenide materials, including the chalcostibnite compounds copper antimony selenide, CuSbSe2. READ MORE

  3. 3. Evaluation of Amyloid Fibrils as Templates for Photon Upconversion by Sensitized Triplet-Triplet Annihilation

    University essay from KTH/Skolan för kemivetenskap (CHE); KTH/Skolan för kemivetenskap (CHE); KTH/Skolan för kemivetenskap (CHE)

    Author : Sharon Berkowicz; Helena Olsson; Henrik Broberg; [2017]
    Keywords : photon upconversion; sensitized triplet-triplet annihilation; anti-stokes emission; amyloid fibrils; whey protein;

    Abstract : In the face of global warming and shrinking resources of fossil fuels the interest in solar energy has increased in recent years. However, the low energy and cost efficiency of current solar cells has up to this date hindered solar energy from playing a major role on the energy market. READ MORE

  4. 4. Organic matter properties and their relation to phosphorus and nitrogen concentrations in Swedish agricultural streams

    University essay from SLU/Dept. of Soil and Environment

    Author : Betty Ehnvall; [2017]
    Keywords : dissolved organic matter; excitation-emission fluorescence spectroscopy; absorbance spectroscopy; eutrophication; biogeochemistry; absorbance index; fluorescence index;

    Abstract : Many agricultural streams in Sweden exhibit high concentrations of nitrogen, phosphorus, suspended sediments and dissolved organic matter (DOM). Together these substances cause eutrophication in streams, rivers and eventually the Baltic Sea. The interactions between different fractions of DOM and nutrients are not very well understood.

  5. 5. The impact on the morphology of the active layer from an organic solar cell by using different solvents

    University essay from

    Author : Robbert Schelfhout; [2017]
    Keywords : organic solar cells; polymer solar cells; morphology of active layer; polymer blend; solvent annealing; spin coating; dip coating; time resolved fluorescence; steady state fluorescence; absorption spectroscopy; atomic force microscopy;

    Abstract : The rise in the world population can be correlated with an increase in energy need. Fossil fuels are not going to able to cover this need in energy because not only are they limited, they also have a negative effect on the environment. A reason the more to switch renewable energy. One of the most popular renewable energy source is solar energy. READ MORE
