Water-oil interfacial kinetics control enables water-based organic solar cells with 12.59% certified efficiency

Organic solar cells (OSCs) are promising for clean-energy generation, but sustainable production remains constrained by hazardous organic solvents. Aqueous organic-semiconductor nanoparticle (NP) inks offer an environmentally friendly route to OSCs, yet low efficiency and limited...

Ambient‐Processed Organic Solar Cells Achieving Nearly 20.5% Efficiency and Industrially Viable Environmental Stability

The ability to process organic solar cells (OSCs) in ambient air is a critical prerequisite for industrial-scale production, as it obviates the need for a high-cost inert atmosphere. However, state-of-the-art cathode interlayers (CILs) typically require strongly hydrophilic group...
