Spiro-MeOTAD

1. 

_{Spiro-OMeTAD  has a high carrier mobility, which means that in the battery, the charge can be transferred from the photosensitive layer to the electrode faster, improving the efficiency of the battery.}

_2.

_{Spiro-OMeTAD has good stability in the REDOX process, which allows it to effectively capture and release charge, while reducing the recombination of charge, improving the long-term stability and efficiency of the battery.}

_3. 

_{Spiro-OMeTAD exhibits a broad spectrum of light absorption performance, which can effectively absorb different wavelengths of light from the solar spectrum and convert it into electric charge.}

_4. 

_{Spiro-OMeTAD can adjust its energy level structure by controlling its doping or adding different ligands, so as to optimize the energy level matching between the photosensitive layer and improve the efficiency of the battery.}

5. 

_{Spiro-OMeTAD is soluble in organic solvents and can be prepared into thin film form by solution processing technology, thus making it easier to use in solar cells.}
