1. Organic Solar Cell Fabrication and Study on the Influence of Spin-dependent Processes on the Photocurrent using Spin-sensitive Techniques
University essay from Uppsala universitet/Fasta tillståndets fysikAbstract : 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.
