The contribution of electron and hole conductivity to the transport loss in organic solar cells
Chen Wang, Toni Seiler, Doyoung Sun +3
The effective conductivity determines the reciprocal of the transport resistance, the dominant loss of fill factor in organic solar cells. We experimentally determine the dependenc…
