1. Alternative back contacts for CZTS thin film solar cells
Sammanfattning : In this thesis, alternative back contacts for Cu2ZnSnS4 (CZTS) thin film solar cells were investigated. Back contacts for two different configurations were studied, namely traditional single-junction cells with opaque back contacts and transparent back contacts for possible use in either tandem or bifacial solar cell configuration.

2. Process development of III-V-based infrared detectors
Sammanfattning : Type-II Superlattice (T2SL) detectors have revolutionized the field of infraredimaging, establishing themselves as the forefront technology in defense, space,and industrial applications. These detectors enable larger formats and higheroperating temperatures (HOT) that minimize the need for bulky and energyconsumingcryogenic cooling, paving the way for imaging systems with reducedSize, Weight, and Power (SWaP).

3. Dynamics of Spent Nuclear Fuel Dissolution : Impact of Catalysis, Matrix Composition and Time Evolution
Sammanfattning : Worldwide, nuclear power produces a large portion of the electricity that we consume every day. While nuclear energy comes with certain advantages, waste originating from its use is of particular concern. LÄS MER
4. Electrochemical Investigation of the Reaction Mechanism in Lithium-Oxygen Batteries
Sammanfattning : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. LÄS MER
5. Ge/high-k Gates for Monolithic 3D Integration
Sammanfattning : Continuous scaling of transistor dimensions has been in the heart of semiconductorindustry for many years. Recently the scaling has been enabled by various performance boosters which resulted in increased processing complexity and cost, forcing the chip manufacturers to look for some alternative solutions.
