1. 6. 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 fysik

   Author : Ronja Olsmats Baumeister; Evelina Roxner; [2022]
   Keywords : EDMR; EPR; trEDMR; PEDOT:PSS; PCBM; P3HT; organic solar cells; osc; opv;

   Abstract : 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.
