Revealing fundamentals of charge extraction in photovoltaic devices through potentiostatic photoluminescence imaging

Michael Graetzel, Shaik Mohammed Zakeeruddin, Yuhang Liu, Dmitry Bogachuk

The photocurrent density-voltage (J(V)) curve is the fundamental characteristic to assess opto-electronic devices, in particular solar cells. However, it only yields information on the performance inte-grated over the entire active device area. Here, a met ...
