"TOP-HTM-α2: A Hole-transporting Material Enhancing the Conversion Efficiency and Stability of Perovskite Solar Cells
TOP-HTM-α2 is being developed as a hole transport material (HTM) for perovskite solar cells (PSCs).1)
When TOP-HTM-α2 is incorporated into perovskite solar cells with a MAPbI3 perovskite layer,
comparable conversion efficiency to devices using Spiro-OMeTAD, a well-known HTM, have been achieved.
Notably, additive-free TOP-HTM-α2 demonstrates high conversion efficiency similar to its additive-containing
counterparts in contrast to the Spiro-OMeTAD-based devices, and achieves a good operational stability higher
than additive-containing Spiro-OMeTAD devices. In addition, additive-containing TOP-HTM-α2 has recently
shown high conversion efficiency in devices using a triple cation perovskite layer. Particularly,
when a low-boiling-point solvent dichloromethane is used in spin-coating, TOP-HTM-α2 exhibits
a remarkable conversion efficiency of 20.18%, which is higher
than 18.85% achieved by Spiro-OMeTAD-based devices.
This result is indicated to be related to its more uniform film surfaces.2)
Additionally, high conversion efficiency and its stability are reported in additive-free
TOP-HTM-α2 devices using FAPbI3 as a perovskite layer.3)
These results highlight the potential of TOP-HTM-α2 as a HTM in various perovskite solar cell
devices and is expected to contribute to research and industrialization of perovskite solar cells.
