Chemical-based gas sensors typically have good sensitivity to the target gas and can detect a variety of gases. However, after being exposed to the target gas, certain chemical-based gas sensors either did not recover at all or did not recover adequately. It is believed that the performance of a chemical-based gas sensor, notably its recovery characteristic, can be impacted by the binder...

The development of efficient, lead-free tandem perovskite solar cells (TPSCs) has become a vital area of study in the quest for sustainable and high-performance photovoltaic technology. An essential challenge in enhancing the power conversion efficiency (PCE) of these devices is the optimisation of the hole transport layer (HTL), which is vital for charge collection and device stability. In...

This research investigates the critical role of defects in the absorber and interface layers of organic-inorganic lead halide perovskite solar cells (PSCs), with a specific emphasis on methylammonium lead triiodide (MAPbI3) PSCs that utilize doped polyaniline/graphene oxide (PANI/GO) as the hole transport layer (HTL). The study employs numerical simulations to comprehensively analyse...

Perovskite solar cells (PSCs) have emerged as a leading technology in photovoltaics, producing remarkable efficiency and cost-effective production methods. Copper(I) thiocyanate (CuSCN) has garnered attention as an effective hole transport layer (HTL) in PSCs due to its advantageous electronic properties, high stability, and excellent hole mobility. This study investigates the effects of...

Highly transparent and uniform planar surfaced Copper Iodide (CuI) film exhibits intriguing morphological properties by presenting Monoethanolamine (MEA) as the green solvent for CuI, thus yielding a comparable outcome of the hole transport layer (HTL) for perovskite solar cell (PSC) applications. The γ-CuI with a zinc-blende structure can be successfully synthesized at a relatively low...

The field of wireless communication has seen significant growth during the past several years. The 5G network was intended to be developed to address the underlying issues with the quality of services in current networks. Based on the new modulation and transmission techniques of 5G technology, the efficiency of data transfer speeds will be improved by more than 10 Gb/s compared to 4G. This...

Advanced communication technologies in 5G networks has the potential to transform the interaction of transportation system between vehicles, infrastructure and padestrians. This study focusses on developing a C-V2X communication model using OMNeT++ simulation tool and analyzing its performance based on key Quality of Service (QoS) factors such as latency, throughput and packet loss in 5G...

The development of novel gas sensing materials that operate effectively at room temperature is crucial for improving environmental monitoring systems, particularly the sensitive detection of carbon dioxide (CO₂). Europium oxide (Eu₂O₃) has potential as a sensing material but lacks sufficient sensitivity, stability, and response time at room temperature, making it insufficient for real world...
