| Abstract Scope |
The transition to sustainable solar technologies requires fabrication strategies that combine high efficiency with low environmental impact and scalability. Metal halide perovskite photovoltaics (MHP-PVs) are promising candidates due to their excellent power conversion efficiencies (PCEs) and tunable properties. However, their development is constrained by toxic solvents such as N,N-dimethylformamide (DMF), recently banned for industrial use in the EU. Traditionally, DMF mixed with dimethyl sulfoxide (DMSO) has been the benchmark solvent system, but this study explores a greener alternative: DMSO-only formulations for ambient-processed semitransparent perovskite solar cells (PSCs). The influence of eco-friendly anti-solvents, isopropanol (IPA) and ethanol (EtOH), was systematically investigated. IPA-treated DMSO-only devices reached 14.7% PCE – lower than DMF:DMSO devices (~21.3%) – yet demonstrated higher light utilization efficiency (4.0%) due to improved visible transmittance. These results establish solvent and anti-solvent engineering as key to scalable, eco-friendly PSCs for applications in BIPV, agrivoltaics, and smart windows. |
