  1. 1. Swedish School-leaving Students' Oral Proficiency in English : Grading of Production and Analysis of Performance

    Author : Stellan Sundh; Merja Kytö; Torsten Lindblad; Sauli Takala; Uppsala universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Linguistics; second language learning; oral testing; rating criteria; oral proficiency; grading spoken English; student production; validity; reliability; 19-year-old Swedish learners; Lingvistik; Linguistics; Lingvistik; English; Engelska;

    Abstract : This study deals with the testing and grading of Swedish school leaving students’ oral proficiency in English, and with certain aspects of these students’ linguistic competence. The analyses and results are based on material drawn from an assessment project carried out at Gothenburg University in 1993. READ MORE

  2. 2. ZrN Back-Contact Reflectors and Ga Gradients in Cu(In,Ga)Se2 Solar Cells

    Author : Sebastian Michael Schleussner; Marika Edoff; Tobias Törndahl; Uwe Zimmermann; Dieter Schmid; Uppsala universitet; []
    Keywords : Solar cells; CIGS; ZrN; three-stage process; multi-stage process; grading; SIMS; electrical modelling; NATURAL SCIENCES; NATURVETENSKAP; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : Solar cells constitute the most direct way of converting solar energy to electricity, and thin-film solar-cell technologies have lately been growing in importance, allowing the fabrication of less expensive modules that nonetheless have good power-conversion efficiencies. This thesis focuses on solar cells based on Cu(In,Ga)Se2, which is the thin-film technology that has shown the highest conversion efficiency to date, reaching 20. READ MORE

    Abstract : A wide range of medical examinations are using analysis of images from different types of equipment. Using artificial intelligence, the assessments could be done automatically. READ MORE

  5. 5. 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
