摘要： The development of air-stable unipolar n-type semiconductors with good solubility in organic solvents at room temperature remains a critical issue in the field of organic electronics. Moreover, most of the existing semiconducting materials exhibit LUMO energy levels higher than −4.0 eV, making electron transport sensitive to both moisture and oxygen. Bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof are disclosed herein. More specifically, bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof for use in organic electronics are disclosed. A process for the preparation of bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide and derivatives is also disclosed. The bis(2-oxoindolin-3-ylidene)benzodifurandione dicyanide or derivatives thereof are characterized by high electron mobilities and are suitable for use as n-type semiconductors in organic electronics.

摘要： Methods and systems for reducing solar cell degradation are provided. The methods and systems related to frequently applying large reverse bias current-voltage (J-V) sweeps to the cell to reduce the rates of internal degradation of the solar cells. The frequent sweeps serve to detrap charge carriers formed in the cell due to photo-oxidative damage. This detrapping reduces the rate of power conversion efficiency (PCE) degradation throughout the life of the solar cell.
