Solid-state dye-sensitised solar cells (ssDSCs) are of huge interest within the scientific community due to the attractiveness of renewable energy sources that are compatible with robust and inexpensive manufacturing technologies like inkjet and roll-to-roll thin-film printing. Spiro-OMeTAD is the classical hole transport material (HTM) used in ssDSCs, however, it requires an expensive synthesis route and has a low charge-carrier mobility and pore-filling ability.

Furthermore, this classical HTM requires certain humidity and oxygen exposure under light soaking conditions for best performance when applied in ssDSCs. Therefore, our research aims at developing new HTMs (or charge transport materials, CTMs) which have diverse properties and that are easy to process for application in ssDSCs.
