Design, synthesis, and characterization of hole transport materials for perovskite solar cells

Benjamin Brandes, Björn A. Weber, René Csuk

Abstract


Perovskite solar cells (PSC) are one of the most promising emerging photovoltaic technologies for a sustainable and profitable energy economy. However, finding alternative, stable, and cheap hole transport materials (HTM) required for these devices is one of the bottlenecks alongside finding optimal manufacturing processes to increase the market viability further. Here we show the synthesis and characterization of six small conjugated molecules HTMs and discuss their viability for future applications. For further validation, DFT calculations were carried out to underline the usability of the HTMs. In the future, these HTMs might help build cheaper and more efficient PSCs. Additionally, this work offers an insight on how to evaluate HTMs without needing to assemble a PSC. Finally, this work might help boost research efforts also for research groups with limited instrument availability.
