Topic: Innovative Chemical Synthesis for High-Performance Organic Solar Cells: Materials and Mechanistic Insights

Organic photovoltaics (OPVs) represent a transformative technology in the pursuit of sustainable energy, celebrated for their low carbon footprint, swift energy payback, and compatibility with scalable manufacturing processes like roll-to-roll printing and open-air fabrication. Recent advancements in chemical synthesis, particularly the design of non-fullerene acceptors, polymer acceptors, and donor molecules, have propelled power conversion efficiencies (PCE) beyond 20%, bringing OPVs closer to commercial adoption.

This Special Issue aims to advance the understanding and development of OPVs through innovative chemical synthesis strategies that enable precise tuning of key material properties, including bandgap alignment, charge transport efficiency, and photostability. Addressing critical challenges such as simplifying synthetic pathways, enhancing long-term material stability, and scaling up environmentally friendly fabrication techniques, this collection integrates cutting-edge molecular design with state-of-the-art characterization and computational methods. It seeks to provide a comprehensive roadmap for positioning OPVs as a cornerstone of renewable energy technology.
