1. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

2. Application demonstrator for green IoT unit including Ligna S-power
Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakultetenSammanfattning : Ligna Energy has developed a printable battery, called S-Power. It is based on research in organic electronics. In order to demonstrate the functionality of the new batteries, an IoT device was developed. The demonstrator consisted of a Sensor for temperature and relative humidity (RH), LoRWAN communication and a circuit for energy harvesting. LÄS MER
3. Solar Energy Harvesting for Outdoor Applications
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : The use of solar cells as a solution for different energy harvesting applications has seen a significant growth during the last few years. With recent advances in the power conversion efficiency and manufacturability of organic photovoltaic cells these systems can be made even cheaper and more available for consumers, opening up new ways for solar technology to be implemented into products.
