   Sammanfattning : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. LÄS MER

3. 12. Planning for Solar Buildings in Urban Environments

   Författare :Jouri Kanters; Avdelningen för Energi och byggnadsdesign; []
   Nyckelord :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;

   Sammanfattning : 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. 13. Power-generation, Power-electronics and Power-systems issues of Power Converters for Photovoltaic Applications

   Författare :Björn Lindgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power systems; bang-bang control; shading tolerance; power quality; photovoltaic; embedded generation; current control; solar power generation;

   Sammanfattning : The thesis deals with issues related to solar energy systems, or more specifically, the electric systems of photovoltaic (PV) installations. Initially aspects of planning and estimating the performance of a PV-installation are considered. LÄS MER

5. 14. Functional Materials for Perovskite Solar Cells

   Författare :Wei Zhang; Lars Kloo; Neil Robertson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; perovskite solar cell; photovoltaic device; lead-free light absorbers; hole-transport materials; coordination complexes; p-type dopants; organic salts; surface passivation.; Kemi; Chemistry;

   Sammanfattning : Energy plays a significant role in our daily lives, but most energy provided by fossil fuels causes serious environmental problems including air pollution, global warming, and ecological damage. In addition, it has been estimated that all of our fossil fuels will run out in 2088 and thus it is highly important to study and apply renewable energy sources. LÄS MER

7. 15. Improved Self-Consumption of Photovoltaic Electricity in Buildings : Storage, Curtailment and Grid Simulations

   Författare :Rasmus Luthander; Joakim Widén; Joakim Munkhammar; Ewa Wäckelgård; Nicholas Etherden; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaics; Solar energy; Self-consumption; Grid integration; Distributed generation; Energy storage; Curtailment; Power system; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Sammanfattning : The global market for photovoltaics (PV) has increased rapidly: during 2014, 44 times more was installed than in 2004, partly due to a price reduction of 60-70% during the same time period. Economic support schemes that were needed to make PV competitive on the electricity market have gradually decreased and self-consumption of PV electricity is becoming more interesting internationally from an economic perspective.
