The present review presents the application of electronically conducting polymers (conducting polymers) as hole conductors in solid-state dye solar cells (S-DSSCs). At first, the basic principles of dye solar cell operation are presented. The next section deals with the principles of electrochemical polymerisation and its photoelectrochemical variety, the latter being an important, frequently-used technique for generating conducting polymers and hole conductors in DSSCs. Finally, two varieties of S-DSSC configurations, those of dry S-DSSC and of S-DSSCs incorporating a liquid electrolyte, are discussed.

This paper demonstrates real-time, label-free, contact-based glucose sensor design of inset-fed Microstrip Patch Antenna (MSPA) genres: Slotted Microstrip Patch Antenna (SMSPA) and Through-hole Microstrip Patch Antenna (THMSPA). In SMSPA, multiple slots are created along the width edge of the patch. In THMSPA, a through-hole is introduced across the antenna including all the layers: patch, substrate and ground conductor of the MSPA.

Multi-layer conductive structures, especially those with features like bolt holes, are vulnerable to hidden corrosion and cracking, posing a serious threat to equipment integrity. Early defect detection is vital for implementing effective maintenance strategies. However, the subtle signals produced by these defects necessitate highly sensitive non-destructive testing (NDT) techniques.

Printable mesoscopic perovskite solar cells (p-MPSCs) provide an opportunity for low-cost manufacturing of photovoltaics. However, the performance of p-MPSCs is severely compromised by iodine defects. This study presents a strategy by incorporating polyaniline (PANI) to achieve both iodine recycling and iodine defect passivation to significantly improve the performance of p-MPSCs.

The charge transfer (CT) reactions in nucleic acids are crucial for genome damage and repair and nanoelectronics using DNA as a molecular conductor. Previous experimental and theoretical works underlined the significance of nucleic acid structural dynamics on CT kinetics, requiring models that incorporate the dynamics of the nucleic acid, solvents, and counterions. Here, we investigated hole transfer kinetics in poly adenine single and double strands at various temperatures and the rate enhancement due to adenine-to-7-deazaadenine mutation by means of a QM/MM approach.

Functional properties of mixed ionic electronic conductors (MIECs) can be radically modified by (de)insertion of mobile charged defects. A complete control of this dynamic behavior has multiple applications in a myriad of fields including advanced computing, data processing, sensing or energy conversion. However, the effect of different MIEC's state-of-charge is not fully understood yet and there is a lack of strategies for fully controlling the defect content in a material.
