16. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells
Abstract : This thesis is divided into four parts with organic chromophores for dye sensitized solar cells as the common feature and an introduction with general concepts of the dye sensitized solar cells. The first part of the thesis describes the development of an efficient organic chromophore for dye sensitized solar cells. READ MORE

17. Studies of Semiconductors Modified with Nanoscale Light Absorbers for Solar Cell Application
Abstract : Recently, materials such as hole conductors (CuI, CuSCN) and light absorbers (Ru-complexes, CuInS2) have been actively investigated for application in nanocrystalline solar cells. In this thesis combinations of these materials have been studied. READ MORE

18. Nanoplasmonics for solar cells
Abstract : 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. READ MORE

19. Dye-sensitized nanostructured metal oxide electrodes : Photoelectrochemical, quantum chemical and electron spectroscopic studies
Abstract : Solar cells based on dye-Sensitized nanostructured electrodes are promising for solar energy conversion. High overall light-to-energy conversion efficiencies have been obtained for systems based on TiO2 (7%) and ZnO (2%). The photocurrent losses in these electrodes have been investigated by photoelectrochemical methods. READ MORE

20. Dynamics of Photoinduced Processes in Dye-Sensitized Nanocrystalline Semiconductor Films--Reactions in the Photoactive Part of the Grätzel Solar Cell
Abstract : The key materials used to convert solar energy into electricity in the Grätzel-type solar cells are dye molecules and titanium dioxide particles attached to each other. The former are similar to those in common products like purple pigments in blueberry juice, while the latter are like sunscreen, white paint, or toothpaste. READ MORE
