Green solvent-printed high-performance perovskite solar cells |
| 초록 |
Over the past decade, Perovskite Solar Cells (PSCs) become a leader in solar cell research, attaining an efficiency of 25.7%. However, polar aprotic solvents for perovskite dissolution and organic solvents for carrier transport layers are toxic for human health . Here, we report green solvent-printed PSCs using the D-bar coating process. Total layers have been printed using spin-coating and D-Bar coating which consist of water, γ-Butyrolactone(GBL)/Dimethyl Sulfoxide(DMSO), 2-Methyl Tetrahydrofuran(2-MeTHF). This DMF-free alternative solvent-based fabrication also shows a wide processing window than toxic precursors. Furthermore, it obtains dense and uniform perovskite film without pinholes leading to the excellent optoelectronic properties of the perovskite film. A champion efficiency of 19.2% is obtained by green solvent printing in ambient conditions. The eco-friendly process sufficiently fulfills the industrial requirement lowering the risk in the health and environmental fields. |
