Charge-generating mid-gap trap states define the thermodynamic limit of organic photovoltaic devices

The inability to accurately measure the charge-generating energy states in organic solar cells makes elucidating the photovoltaic effect in these devices difficult. Here, the authors report charge-generating mid-gap trap states in organic solar cells via ultra-sensitive photovoltaic measurements.
