Stability and Processing Strategies for Organic and Hybrid Semiconductors

Dear Colleagues,

Organic semiconductors and organic–inorganic hybrid materials have emerged as promising platforms for next-generation optoelectronic technologies, including photovoltaics, light-emitting diodes (LEDs), sensors, and flexible electronics. Yet their widespread deployment remains critically constrained by insufficient operational stability. Devices frequently exhibit rapid performance decay, pronounced sensitivity to environmental stressors, and limited lifetimes, all of which undermine scalability, compromise reliability, and restrict integration into real-world applications. While efficiency improvements—such as enhanced power conversion or brighter emission—have driven remarkable progress, stability has often been treated as secondary. This imbalance has created a fundamental bottleneck, highlighting the urgent need to elevate durability and reproducibility as core design metrics alongside efficiency to enable practical and sustainable implementation.

Taking the above into account, we are pleased to invite you to contribute to the Special Issue “Stability and Processing Strategies for Organic and Hybrid Semiconductors” in Processes.

This Special Issue aims to gather high-quality contributions that address synthesis, processing, characterization, and stability enhancement of these materials for optoelectronic and photovoltaic applications. By bringing together original research and critical reviews, this collection seeks to advance understanding of degradation mechanisms, propose innovative mitigation strategies, and highlight scalable approaches for reliable device integration.

In this Special Issue, short communications, original research articles, and minireviews are welcome. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment. Research areas may include (but are not limited to) the following:

• Green synthesis of organic and hybrid semiconductors
• Process optimization and advanced processing techniques and scalable fabrication methods
• Structural and compositional engineering for improved stability
• Degradation mechanisms and mitigation strategies under thermal, chemical, and photonic stress
• Interface engineering and defect passivation, including applications in Hole Transport Layers (HTL) and Self-Assembled Monolayers (SAM’s)
• In situ and operando characterization of stability and performance
• Computational modeling and predictive design for reliability
• Application-driven studies in photovoltaics, LEDs, sensors, and flexible electronics
• Scale-up strategies and industrially relevant processing methodologies for organic and hybrid semiconductors

We look forward to your valuable contributions to this Special Issue, which will provide a timely and comprehensive overview of stability-focused strategies for organic and hybrid semiconductors.
