Synthesis of 10H-Phenothiazines for Investigation of Π-linker Effect in Dye-Sensitized Solar Cells

Abstract

A global challenge is that electricity is predominantly generated unsustainably. To improve on the situation, more of the electricity should be generated directly from sunlight by solar cells. Commercial solar cells based on crystalline silicon have increased their efficiencies over the years. However, their widespread global use is hampered by a high production cost. Alternative solar cell technologies are therefore of great interest and one of the most promising candidates is dye-sensitized solar cells (DSSCs), also termed Grätzel cells. The objective of this project is to synthesise building blocks and dyes to aid development of new DSSCs. The purpose of this thesis is both to generate chemical knowledge on synthesis and investigate design concepts for dyes for DSSC.
