On the origin of tail states and VOC losses in Cu(In,Ga)Se2
Omar Ramírez, Jiro Nishinaga, Felix Dingwell +5
The detrimental effect of tail states on the radiative and non-radiative voltage loss has been demonstrated to be a limiting factor for the open circuit voltage in Cu(In,Ga)Se2 sol…

Metastable defects decrease the fill factor of solar cells
Thomas Paul Weiss, Omar Ramírez, Stefan Paetel +4
Cu(In,Ga)Se2 based solar cells exceed power conversion efficiencies of 23 %. Yet, the fill factor of these solar cells, with best values around 80 %, is relatively low (Si reaches…
