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...

Over 20% Efficiency in As–Cast Organic Solar Cells Enabled by Flory–Huggins Parameter Engineering

ABSTRACT The realization of high–efficiency as–cast organic solar cells (OSCs) represents a key step toward simplified processing and scalable fabrication for commercialization. However, achieving high–performance as–cast devices remains challenging because it demands delicate ba...

Tailoring Vertical Exciton Dissociation Pathways via Hydrogen Bonding for High‐Performance Thick‐Film Organic Solar Cells

ABSTRACT Organic solar cells (OSCs) with thick active layers demonstrate significant potential for scalable roll‐to‐roll manufacturing in industrial applications. However, increasing the active layer thickness triggers unfavorable morphological evolution, compromising vertical ex...

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...
