1. Organic Solar Cell Fabrication and Study on the Influence of Spin-dependent Processes on the Photocurrent using Spin-sensitive Techniques
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysikSammanfattning : Research in recent years on novel materials in organic solar cells (OSCs) have contributed to a rapid advancement in OSC efficiency. Here, OSCs with the well-studied organic semiconductors poly(3-hexylthiophene):[6,6]-phenyl C60-butyric acid methylester (P3HT:PCBM) in a bulk heterojunction structure were prepared to establish a baseline procedure for fabrication and spin-sensitive spectroscopy.

2. Characterization of Graphene-Based Anisotropic Conducting Adhesives : A study regarding x-ray sensing applications
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : A common method of cancer treatment is radiation therapy. In radiation therapy, a treatment planning system is made to specify the dose of X-rays needed to eradicate the tumor. To assure the right amount of X-ray dosage a quality assurance is using a phantom containing radiation sensors. LÄS MER
