1. 1. Sputtered Transparent Contact Layers for Bifacial and Tandem Solar Cells

   University essay from Uppsala universitet/Solcellsteknik

   Author : Klara Kiselman; [2022]
   Keywords : Solar cells; ITO; indium doped tin oxide; bifacial cell; tandem cell; transparent conductive oxides;

   Abstract : A key to solar cells with lower environmental impact is higher efficiency and reduced material usages. Bifacial solar cells may have a higher efficiency as light can enter from two directions and tandem solar cells may use a larger part of the incoming solar spectrum, increasing the efficiency.

3. 2. MFC for paper surface treatment

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Yselaure Boissard; [2017]
   Keywords : microfibrillated cellulose; MFC; cellulose nanofibers; CNF; paper; coating; barrier;

   Abstract : In this study, microfibrillated cellulose (MFC) was applied in an aqueous suspension as a coating material on paper substrates. Two different coating techniques were used: rod coating and size press. READ MORE

4. 3. X-Ray Photoelectron Spectroscopy of Metal & Metal-based Clusters: Au, Ag & Sn Cases.

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Charles Wright; [2016]
   Keywords : Physics; Photoelectron; Spectroscopy; Cluster; Clusters; Gold; Silver; Tin; Synchrotron; X-Ray; Physics and Astronomy;

   Abstract : Clusters are particles which consist of a finite number (2 − 10 ^6−7 ) of atoms/molecules. For the work presented in this thesis free clusters have been produced in order to study their properties, free of interfering substrates, using photoelectron spectroscopy at the MAX-lab synchrotron facility in Lund, Sweden.

5. 4. Diode laser spectroscopy for oxygen detection in the lungs of infants

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Peilang Liao; [2016]
   Keywords : GASMAS; Tunable laser; Transport theory; 3D phantom; Diagnoses; Gas; Lung; Physics and Astronomy;

   Abstract : This thesis work is part of a larger project with final goal to be able to measure the oxygen concentration in the lungs of infants, using non-invasive laser spectroscopy. This thesis is specifically dealing with simulations of light transport through the upper body of infants, as well as constructing a tissue-like model (phantom) that can be used in experiments.

6. 5. Evaluating the Origin of Water Vapour in Giant Stars

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Mohsen Farzone; [2013]
   Keywords : Physics and Astronomy;

   Abstract : The advent of infrared astronomy, unlike optical astronomy that was developed over centuries, was delayed until the space age due to our own atmosphere acting as an efficient shield towards this radiation. With a lot of molecules (including water) emitting in the infrared region, it was first in the late 1990s that water no longer was deemed special and was observed in many cooler (K-M) giant stars.
