David Mitzi and co‐workers have studied defects in Cu(In,Ga)Se 2 (CIGS), intentionally induced with controlled processing, with both material and device characterization techniques on p. 845 . Structural defects indentified are directly correlated with defect levels extracted from admittance spectroscopy and device behaviors. Reduction of such defects leads to significant improvement of the device photovoltaic performance.
