Surface passivation of Na in flexible kesterite thin-film deposited with different precursor stack orders |
| 초록 |
Flexible and high-efficient CZTSSe thin-film solar cell were successfully fabricated by a sputtering method. Especially, in order to avoid forming unwanted secondary phases, we varied the condition for thin-film deposition. To figure out the carrier behavior in the materials, we introduced photo-assisted atomic force microscopy (AFM). Photo-assisted Kelvin probe force microscopy (KPFM) can measure the current flow induced by the lights, showing them on the thin-film surface. In particular, the surface photovoltage (SPV) has increased with Na passivation, indicating the enhanced carrier lifetime. In this way, we can figure out how the deposition condition can affect the thin films’ structural and optoelectrical properties, thus solar cell performances. |
