Development of Photoelectrochemical Sensors

Topic Information

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.

To overcome the bandwidth and power limitations of traditional multi-chip architectures in inter-satellite laser communication ATP (Acquisition, Tracking, and Pointing) systems, we propose a highly integrated hardware-software co-design imaging system. It integrates a CMV4000 sensor and an XCKU060 FPGA with an embedded Loongson LA132 soft core. To resolve thermal-induced timing misalignments at 180 fps, an LVDS dynamic phase compensation and multi-stage synchronization mechanism is introduced, ensuring error-free capture. Furthermore, a least-squares circle-fitting algorithm with nonlinear error compensation mitigates spot distortion and occlusion from strong background noise. Results confirm that the system stably outputs 2048 × 2048 resolution images. Notably, under extreme conditions (5 dB SNR, 60% spot loss), the positioning RMSE (Root Mean Square Error) remains strictly within 1.5 pixels. This approach optimizes SWaP (Size Weight and Power) metrics, delivering a robust, high-precision solution for spaceborne ATP systems. Full article
