2. 1. Business Intelligence through a sociomaterial lens : The imbrication of people and technology in a sales process

   Author : Tobias Christian Fischer; Einar Iveroth; Jan Lindvall; Mathias Cöster; Christina Keller; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; big data; business intelligence; business intelligence systems; data analytics; digital transformation; imbrication; sales process; sociomateriality; sociomaterial imbrication model; work shadowing;

   Abstract : Digitalization and digital devices are on the rise, and as a result, many new products and services have been developed, which has led to greater interaction between people and technology. This thesis explores the interaction between people and technology by looking at the daily use of a business intelligence (BI) system in an automotive company’s sales process, where sellers use the system to analyze, report, and measure sales performance.

4. 2. Window Layer Structures for Chalcopyrite Thin-Film Solar Cells

   Author : Fredrik Larsson; Tobias Törndahl; Jan Keller; Marika Edoff; Daniel Lincot; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CIGS; atomic layer deposition; ALD; thin-film technology; window layer structures; buffer layers; front contacts; metal oxides; ternary compounds; CIGS; tunnfilmssolceller; ALD; tunnfilmsteknik; fönsterlager; buffertlager; framkontakter; metalloxider; ternära föreningar; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : This thesis aims to contribute to the development of improved window layer structures for chalcopyrite thin-film solar cells, with an emphasis on the buffer layer, to assist future reductions of the levelized cost of energy. This is realized by exploring the potential of existing materials and deposition processes, as well as developing new buffer layer processes based on atomic layer deposition (ALD). READ MORE

5. 3. In the confines of Cu(In,Ga)Se2 thin film solar cells with rear surface passivating oxide layers

   Author : Dorothea Ledinek; Marika Edoff; Charlotte Platzer Björkman; Jan Keller; Christian Kaufmann; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali; Alumina; Back contact; CIGS; CIGSe; Hafnia; Passivation; Rear contact; Sodium fluoride; Ultra-thin; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : The material supply to build renewable energy conversion systems needs to be considered from both a cost and an energy security perspective. For Cu(In,Ga)Se2 (CIGS) thin film solar cells the use of indium in the absorber layer is most problematic. READ MORE

6. 4. Electrical Characterisation of (Ag,Cu)(In,Ga)Se2 Thin Film Solar Cells To Investigate Stability

   Author : Patrick Pearson; Charlotte Platzer Björkman; Jan Keller; Jörgen Olsson; Gerrit Boschloo; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Cells; Stability; Electrical Characterisation; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : This licentiate thesis gives a summary of electrical characterisation techniques, detailing their use to investigate and understand stability and meta-stability in thin-film solar cells, with a focus on the chalcopyrite material system. Experimental data is used to illustrate the information that can be extracted with these measurements, highlighting the deeper insights that can be drawn from complementary measurements. READ MORE
