Abstract
The enthusiasm for renewable energy technologies is growing exponentially, with researchers from various fields actively engaged in the development of more sustainable and environmentally friendly solutions. Deep eutectic solvents have found extensive applications in numerous fields due to their eco-friendly attributes, ranging from eco- conscious synthesis processes to environmentally benign industrial practices offering many opportunities and opening up attractive perspectives. However, their utilization in emerging solar technologies, where abundant and clean solar energy addresses crucial societal needs, remains relatively limited. This poses a significant constraint, as numerous solar devices incorporate harmful or hazardous elements, thereby severely impeding their environmentally friendly characteristics. The majority of electrolytes that utilize a deep eutectic solvent for dye sensitized solar cells feature an ammonium-based hydrogen bond acceptor; however, many electrolytes feature co-solvents and additives that convolutes these complex electrolyte systems. The work presented here delves into ammonium-based deep eutectic solvent electrolyte systems for dye-sensitized solar cells in an attempt to arrive at a more fundamental understanding of the behavior of the deep eutectic solvent, investigating individual components, halide ions, and derivatives of well-known and novel deep eutectic solvents.
