1. 16. System Studies and Simulations of Distributed Photovoltaics in Sweden

   Författare :Joakim Widén; Ewa Wäckelgård; Brian Norton; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaics; Solar energy; Distributed generation; Load modelling; Time-use data; Markov chain; Power flow; Power system; Engineering physics; Teknisk fysik; Teknisk fysik; Engineering Science;

   Sammanfattning : Grid-connected photovoltaic (PV) capacity is increasing worldwide, mainly due to extensive subsidy schemes for renewable electricity generation. A majority of newly installed systems are distributed small-scale systems located in distribution grids, often at residential customers. LÄS MER

3. 17. Retrofitted Solar Domestic Hot Water System for Single-Family Electrically-Heated Houses: Development and testing

   Författare :Ricardo Bernardo; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar domestic hot water; retrofitting; single family electrically heated houses; high solar fraction; photovoltaic thermal concentrating hybrids; PVT; parabolic reflectors; CPC thermal collector.;

   Sammanfattning : In Sweden, there are roughly half a million single family houses that use electric heating for both domestic hot water production and space heating. Since electricity is the most expensive energy source in Sweden, it is interesting to install a high solar fraction solar thermal system to reduce the energy use in these houses. LÄS MER

4. 18. Nanoplasmonics for solar cells

   Författare :Viktoria Gusak; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enhanced near-field; adsorption; titanium dioxide; Localized Surface Plasmon Resonance; amorphous hydrogenated Silicon; diffusion; Langmuir kinetics; Dye-Sensitized Solar Cell; plasmonic nanoparticle; mesoporous material; diffusion-front model;

   Sammanfattning : The main source of our energy system, the fossil fuels, will eventually be depleted and also pose environmental and climate hazards. There is thus a need for alternative, renewable energy sources. Solar (photovoltaic) cells will play an important role as one of them. LÄS MER

5. 19. Alternative Energy Harvesting and Conversion Systems Based on Nanostructured Heterostructures

   Författare :Mojtaba Gilzad Kohan; Alberto Vomiero; Andrea Li Bassi; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light harvesting; solar supercapacitors; energy conversion; Photovoltaic; energy storage; metal oxide semiconductors; Experimentell fysik; Experimental Physics;

   Sammanfattning : Conversion and storage of the solar radiation into applicable forms of energy, using ubiquitous materials is of central importance that quests several disciplinary fields in both applied technology and fundamental science. Harnessing the solar energy received by the earth has the potential to replace the current sources of energy and it is imperative for sustainable development. LÄS MER

7. 20. Solar integrated heating systems: Applications in buildings and industries

   Författare :Puneet Kumar Saini; Joakim Widén; Xingxing Zhang; Frank Fiedler; Thomas Olofsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heating systems; Renewable heating systems; Decarbonization; Solar thermal; Techno-economic analysis; Thermal energy storage.; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Sammanfattning : “Heat is half” of the global final energy consumption, and the decarbonization of the heating sector is critical to achieving climate goals. This thesis employs a system modelling approach to evaluate renewable heating systems. LÄS MER
