Solid‐State Dye‐Sensitized Solar Cells Using a Novel Class of Ullazine Dyes as Sensitizers

Here we present the photovoltaic performance of solid‐state dye‐sensitized solar cells (DSCs) using a series of ullazine‐based metal‐free organic sensitizers and spiro‐MeOTAD as a hole‐transport material. A maximum of 4.95% power conversion efficiency measured under standard AM 1.5G illumination (100 mW cm−2) was achieved with the best performing ullazine dye, and was further improved to 5.40% through co‐sensitization with the triphenylamine‐based organic sensitizer, D35. This study investigates the effect of the molecular structure of the ullazine sensitizer on the performance in solid‐state DSCs.
