Abstract Reducing carrier recombination and facilitating charge extraction at the interface is of great significance to improve device performance perovskite solar cells (PSCs) towards commercial use. However, there has been little work done concerning transportation mechanism metal electrode electron transport layer in inverted PSCs. Herein, a new strategy modification reported that leverages unique metal‐to‐insulator transition (MIT) characteristics vanadium dioxide which inserted as (EEL)...
In recent years, there has been a growing trend toward the development of smart buildings that rely on cyber-physical systems (CPS) to optimize occupant comfort, safety, and energy efficiency. To ensure reliable efficient operation CPS with designed control strategies, it is important evaluate their performance under various scenarios before deploying them in real world. This where Hardware-in-the-loop (HIL) testbed for studying sensor control-related studies can be highly valuable. With...
With the progress of times, effective use energy is becoming more and important. Among a lot sources, electric currently most widely used. However, thermal effect conventional conductors affects efficient electrical energy. But superconducting phenomenon presents solution to this problem. This paper first introduces superconductivity, history research on classification materials, explores potential applications materials in various fields. The role computer science particularly prominent....
Water-to-air heat pumps are widely used Heating, Ventilation, and Air Conditioning (HVAC) devices due to their versatility energy efficiency. However, there is a scarcity of readily available Modelica models that support reversible operation (heating cooling modes), use compressor speed as the control signal, accurately predict system performance. To address this gap, paper presents speed-input water-to-air pump model developed using Modelica. Performance curves employed represent...
The thermal masses of components influence the performance many adsorption heat pump systems. However, typically when experimental systems are reported, data on mass missing or incomplete. This work provides original measurements for sorption exchanger hardware. Much this hardware was previously reported in literature, but without detailed data. first values literature to thoroughly account all masses, including transfer fluid. impact system is also discussed, with calculation left future...
Degradation of gold contacts in micro-switches was studied under an extensive range operation conditions including high-electric-field ac/dc hot switching, low-electric-field switching and cold switching. Tests were conducted a unique experimental set-up. Gold micro-contacts characterized by atomic force microscope. It found that material transfer/distribution feature correlated with specific operations. New insights into contact degradation mechanisms achieved analyzing features varied...
A novel test facility for the efficient evaluation of microelectromechanical system (MEMS) switches and development alternative contact materials is described. The utilizes upper cantilever from commercial MEMS switches, tests these against bottom within a modified atomic force microscope (AFM). closely approximates real switch, but can accommodate wider range conditions materials. allows to be easily quickly incorporated, therefore evaluated by measuring number cycles failure. evolution...
We designed and fabricated a high extinction ratio silicon Mach-Zehnder thermo-optic switch with variable splitter spiral phase shifters. The proposed TO can achieve ratios over 38 dB from 1520 nm to 1580 for both bar-port cross-port maximum value 45 around 1560 nm. In addition, the lower power consumption than conventional on same chip is extremely tolerant imbalance of MMI 3-dB splitter. This has great potential large scale integration applications.
AbstractOver the last decade, global fight against climate change through electrification has led to an increase in research on building heating, ventilation, and air conditioning (HVAC) systems that utilize intelligent control algorithms provide demand-side grid service while also maintaining thermal comfort of occupants. As pivotal point between electricity consumption indoor comfort, high-efficiency electrical vapor-compression heat pumps are at center these emerging studies, various...
The van der Pauw Hall effect measurements from 77–350 K are reported for a series of p-type nitrogen-doped ZnSe thin films. Epitaxial HgSe electrodes were used as ohmic contacts in these experiments.
