Radical p-Doping Spiro-OMeTAD for Efficient, Stable and Self-Healing Flexible Perovskite Solar Cells
{{output}}
Spiro-OMeTAD is the primary hole transport material (HTM) for high-efficiency and stable flexible perovskite solar cells (FPSCs). However, the slow oxidation rate and susceptibility to film cracking under stress in Spiro-OMeTAD lead to reduced device stability... ...
