1. Interfacial Analysis and Charge Transfer in Solar Cells
Sammanfattning : Harnessing sunlight through solar cells is vital for sustainable energy production. The conventional architecture of a solar cell consists of multilayers of materials, each serving a particular function. The absorbing layer converts the solar energy into valuable electricity by the photovoltaic effect. LÄS MER
2. Synthesis and Modification of Conjugated Materials for Polymer Solar Cells
Sammanfattning : Polymer solar cells have emerged as a promising alternative to silicon based solar cells. One of the advantages of polymer solar cells is the possibility to use roll-to-roll techniques for large-scale device production. However, in order to fully utilize this technique, several issues need to be resolved. LÄS MER
3. Nanoparticle plasmonics for solar cell applications
Sammanfattning : The energy demand of society increases rapidly, while the main source of today’s energy, the fossil fuels, eventually will be depleted and also poses environmental and climate hazards (though the global warming). Therefore there is a need for alternative, renewable energy sources, and solar photovoltaics (solar cells) will play an important role as one of them. LÄS MER
4. Materials and interfaces for sustainable organic solar cells
Sammanfattning : Photovoltaics, the apparatus utilizing green solar power to generate electricity, is one of the efficient measures to the continuously increasing energy demand and exacerbated carbon emission of the human civilization. As a candidate with the potential of providing the cheapest and greenest form of electricity, organic solar cells (OSCs) received tremendous scientific interest, resulting in a significant power conversion efficiency (PCE) boosting to above 19% recently.

5. Electronic Structures and Energy Level Alignment in Mesoscopic Solar Cells : A Hard and Soft X-ray Photoelectron Spectroscopy Study
Sammanfattning : Photoelectron spectroscopy is an experimental method to study the electronic structure in matter. In this thesis, a combination of soft and hard X-ray based photoelectron spectroscopy has been used to obtain atomic level understanding of electronic structures and energy level alignments in mesoscopic solar cells.
