1. Exploring Devices for Molecular Solar Thermal Energy Storage Systems
Sammanfattning : The sun is considered to be one of the most abundant and renewable sources of energy. During recent last decades, technologies for solar energy capture and storage have been significantly investigated. An attractive way to store solar light, is to use photochromic molecules that can capture and store solar energy in chemical bonds. LÄS MER
2. Norbornadienes for Solar Thermal Energy Storage and New Applications
Sammanfattning : The energy demand worldwide is steadily increasing, therefore it is fundamental to efficiently utilise renewable energy resources. Energy storage technologies are partic- ularly relevant in order to be able to exploit renewable energy resources such as solar energy, since these are typically intermittent and not evenly distributed.

3. New methods and applications to explore the dynamics of least-cost technologies in geospatial electrification modelling
Sammanfattning : Access to modern energy services is a pre-requisite for sustainable development. As such, Sustainable Development Goal (SDG) 7 aims to ensure access to affordable, reliable, sustainable and modern energy for all. However, as of 2021, 675 million people lack access to electricity, and 2.3 billion people lack access to clean cooking fuels. LÄS MER
4. Year-round production of forest seedlings under LED lamps : Biological and energetic implications of indoor cultivation
Sammanfattning : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. LÄS MER
5. Slow and stopped light by light-matter coherence control
Sammanfattning : In this thesis we study light-matter coherence phenomena related to the interaction of a coherent laser field and the so-called Λ-system, a three-level quantum system (e.g., an atom). We observe electromagnetically induced transparency (EIT), slow and stored light in hot rubidium vapor. LÄS MER
