Loss Analysis of Low Bandgap (Ag,Cu)(In,Ga)Se2 Solar Cells for Tandem Applications
Small, EarlyView.A complete loss analysis has been carried out on the state‐of‐the‐art 1.0 eV bandgap (Ag,Cu)(In,Ga)Se2 solar cells, which are of interest for tandem devices. The most significant loss mechanisms are found in the open‐circuit voltage, due to non‐radiative losses in the chalcopyrite absorber, and in the fill factor, caused by space‐charge region ...

Study of the Electrochemical Passive-Active Transition of Chalcopyrite in Acidic Solution
International Journal of Electrochemical Science, 2016 The electrochemical behaviors of chalcopyrite in 1.0 M H2SO4 were studied by potentiodynamic polarization. The experimental results revealed that chalcopyrite has four different potential ranges: passive for OCP up to 500 mV; trans-passive dissolution ...
