Microstructure Modification: Generation of Crystal Defects and Phase Transformations

Optimizing the structure and optoelectronic properties of cuprite thin films via a plasma focus device as a solar cell absorber layer

“…First, rising plasma shots might result in alterations in the crystal structure or grain size within the thin film. 66 Defects, dislocations, or grain boundaries arising due to increased film thickness or structural changes could contribute to the creation of localized electronic states, leading to the Urbach band tailing. 67 Second, in some cases, the increase in film thickness could influence quantum confinement effects, altering the electronic states within the bandgap and impacting the bandgap energy.…”
