Direct evidence for grain boundary passivation in Cu(In,Ga)Se2 solar cells through alkali-fluoride post-deposition treatments

Grain boundaries play critical roles in determining the properties and performance of solar cells based on polycrystalline materials. Here Nicoara et al. showcase that proper treatments passivate defects at grain boundaries by forming secondary material phases with the CIGSe absorbers and lead to hi...
