1. 1. Copper-based Redox Systems for Dye-sensitized Solar Celles

   Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

   Författare :Rebecca Pernechele; [2017]
   Nyckelord :;

   Sammanfattning : In order to take on the challenge of the world energy issues, there is a necessity to identify alternative energy sources to the fossil fuels. The sun represents the most abundant source of energy, and one way to harvest it is by photovoltaic devices directly converting sunlight into electricity. LÄS MER

3. 2. Simulations of a Ruthenium Complex and the Iodide/Triiodide Redox Couple in Aqueous Solution: Solvation and Electronic Structure

   Magister-uppsats, Institutionen för fysik och astronomi

   Författare :Ida Josefsson; [2010]
   Nyckelord :Dye-sensitized solar cells; molecular modeling; quantum chemistry; molecular dynamics; photoelectron spectroscopy; Färgämnessensiterade solceller; molekylmodellering; kvantkemi; molekyldynamik; fotoelektronspektroskopi;

   Sammanfattning : In dye-sensitized solar cells, the functions of light absorption and charge transport are separated. A photosensitive ruthenium-polypyridine dye in the cell absorbs light, injects an electron to a semiconductor and is then regenerated by a redox couple, typically iodide/triiodide. LÄS MER
