1. Photoelectrochemical studies of dye-sensitized solar cells using organic dyes
Sammanfattning : The dye-sensitized solar cell (DSC) is a promising efficient low-cost molecular photovoltaic device. One of the key components in DSCs is the dye, as it is responsible for the capture of sunlight. State-of-the-art DSC devices, based on ruthenium dyes, show record efficiencies of 10-12 %. LÄS MER
2. Alternative Energy Harvesting and Conversion Systems Based on Nanostructured Heterostructures
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
3. Advanced Metal Oxide Semiconductors for Solar Energy Harvesting and Solar Fuel Production
Sammanfattning : Increasing energy consumption and its environmental impacts make it necessary to look for alternative energy sources. Solar energy as huge energy source which is able to cover the terms sustainability is considered as a favorable alternative. LÄS MER
4. Synthesis and Robotized Screening of Novel Perovskite Materials for Solar Cell Application
Sammanfattning : As of today, the energy consumption in the world is high and is essential in the development and growth of the modern-day society. The world energy consumption is projected to increase significantly over the next decades. LÄS MER
5. Optical modelling of conjugated polymers : from materials to devices
Sammanfattning : Measurements and modelling of theoretical properties of polymer-based photovoltaic devices, PPVDs, are the subjects of this thesis. Modelling refers both to modelling of materials, based on extraction of the dielectric function, and to modelling of devices by computer simulation of the optical electrical field inside PPVDs.
