2. 1. Planning for Solar Buildings in Urban Environments

   Author : Jouri Kanters; Avdelningen för Energi och byggnadsdesign; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architecture; design tool; design process; solar energy; urban planning; photovoltaics; solar thermal; building integration; density; net zero energy buildings; interviews; parametric studies; action research;

   Abstract : Energy use in buildings accounts for a significant proportion of the total energy use in many countries. While past and current buildings have solely been energy consumers, future buildings will, besides using less energy, also need to produce (part of ) the required energy on site with renewables.

4. 2. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

   Author : Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

   Abstract : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. READ MORE

5. 3. 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

6. 4. Imaging spectropolarimetry of solar active regions

   Author : Gautam Narayan; Göran Scharmer; Rolf Schlichenmaier; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sun; Spectropolarimetry; Solar magnetic fields; Sunspots; Plages; Solar physics; Solfysik; Astronomy; astronomi;

   Abstract : Solar magnetic fields span a wide range of spatial scales from sunspots and plages to magnetic bright points. A clear understanding of the physical processes underlying the evolution of these magnetic features requires high-resolution spectropolarimetric observations of solar active regions and comparisons with synthetic data from simulations.

7. 5. Solar heat pump systems for heating applications : Analysis of system performance and possible solutions for improving system performance

   Author : Stefano Poppi; Per Lundqvist; Chris Bales; Kai Siren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heat pump systems; techno-economics; solar thermal; system improvements; cost-effectiveness; Energiteknik; Energy Technology; MacSheep;

   Abstract : Solar heat pump systems (SHPs) are systems that combine solar energy and heat pumps. SHPs have been investigated for several decades and have been proven to increase the share of renewable energy and reduce electric energy demand in residential heating applications. READ MORE
