Development of Photoelectrochemical Sensors

Dear Colleagues,

This Special Issue on Development of Photoelectrochemical Sensors aims to highlight recent advances and emerging applications of photoelectrochemical sensing technologies across diverse scientific and technological fields.

Photoelectrochemical (PEC) sensors have emerged as powerful analytical platforms due to their high sensitivity, low background signal, and excellent signal-to-noise characteristics derived from the synergistic integration of photonic and electrochemical processes. Recent advances in photoactive materials, including semiconductors, nanostructured materials, and hybrid systems, have significantly expanded the performance and applicability of PEC sensors. These developments have enabled rapid, selective, and cost-effective detection strategies across a wide range of analytical challenges.

This Special Issue focuses on the development, characterization, and application of photoelectrochemical sensors in diverse fields such as environmental monitoring, food safety and quality control, biomedical and chemical analysis, electronics, and advanced analytical chemistry. Contributions addressing novel photoelectrode materials, sensor architectures, signal amplification strategies, and coupling with nanotechnology, surface modification, or data-driven approaches are particularly encouraged. Both fundamental studies and applied research demonstrating real-sample analysis, on-site monitoring, and portable or miniaturized PEC systems are welcome.

By bringing together interdisciplinary research, this Special Issue is dedicated to current trends, challenges, and future perspectives in photoelectrochemical sensing and to promoting innovative solutions with strong potential for scientific and technological impact.
