This project was aimed to conduct experimental as well as simulation studies on the application of self-assembling discotic liquid crystalline (DLC) materials to dye sensitized solar cells (DSSCs) and perovskite solar cells (PSCs). DSSCs and PSCs both suffer from stability challenges, due to evaporation of the electrolyte and degradation of the semiconducting materials, respectively. Solving these challenges (combined with their low fabrication costs) will make these technologies competitive with both silicon photovoltaics as well as fossil fuel based electricity generation. This research attempts to address both challenges using mesophasic materials in novel device architectures.
