Heat treatment in an oxygen-rich environment to suppress deep-level traps in Cu<sub>2</sub>ZnSnS<sub>4</sub> solar cell with 11.51% certified efficiency
Nature Energy, Published online: 10 April 2025; doi:10.1038/s41560-025-01756-2The efficiency of pure sulfide kesterite solar cells is limited by deep-level defects. Wu et al. develop a heat treatment in an oxygen-rich environment to suppress sulfur vacancies, achieving an 11.51% certified efficiency.
