  1. 1. Advanced rear contact design for CIGS solar cells

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jorge Alexandre De Abreu Mafalda; [2019]
    Keywords : CIGS; HfO2; surface passivation; alkali treatment; point contact openings; SCAPS;

    Abstract : The current trend concerning the thinning of solar cell devices is mainly motivated by economic aspects, such as the cost of the used rare-earth elements, and by the requirements of emergent technologies. The introduction of ultra-thin absorber layers results in a reduction of used materials and thus contributes to a more cost-effective and time-efficient production process. READ MORE

  3. 2. Development and characterisation of silicon solar cells with recombination interconnects for future tandem solar cells

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Marika Gugole; [2018]
    Keywords : ;

    Abstract : In this project commercial BSF Si solar cells have been processed in order to develop a suitable interconnect for a possible tandem solar cell. The Ag original top contacts have been removed and replaced with TiSi2 formed using the SALICIDE process at 3 different temperatures: 500 °C, 650 °C and 750 °C. READ MORE

  4. 3. Recombination losses in organic solar cells : Study of recombination losses in organic solar cells by light intensity-dependent measurements

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Sebastian Lind; [2018]
    Keywords : Organic solar cells; recombination losses;

    Abstract : Easy manufacturing, light weight and inexpensive materials are the key qualities of organic solar cells that makes them a highly researched area. To make organic solar cells adequate for the market, the efficiency of power conversion has to increase further, and the lifetime of organic solar cells has to improve. READ MORE

  5. 4. Copper-based Redox Systems for Dye-sensitized Solar Celles

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Rebecca Pernechele; [2017]
    Keywords : ;

    Abstract : In order to take on the challenge of the world energy issues, there is a necessity to identify alternative energy sources to the fossil fuels. The sun represents the most abundant source of energy, and one way to harvest it is by photovoltaic devices directly converting sunlight into electricity. READ MORE

  6. 5. Surface Passivation of CIGS Solar Cells by Atomic Layer Deposition

    University essay from KTH/Kraft- och värmeteknologi

    Author : Sara Motahari; [2013]
    Keywords : solar cells; CIGS; thin film; surface passivation; atomic layer deposition;

    Abstract : Thin film solar cells, such as Cu(In,Ga)Se2, have a large potential for cost reductions, due to their reduced material consumption. However, the lack in commercial success of thin film solar cells can be explained by lower efficiency compared to wafer-based solar cells. READ MORE
