Ink stabilization technique for large-area printable quantum dot solar cells
Nature Energy, Published online: 07 April 2025; doi:10.1038/s41560-025-01747-3The poor stability of colloidal quantum dots (CQD) hinders their use in large-area solar cells. A stable printable CQD ink is demonstrated by using solution chemistry engineering to control the surface ions on CQDs to prevent inter-dot fusion. This ink produced a solar module with a power conversion efficiency of over 10%.
