Abstract Crystalline silicon (c-Si) heterojunction (HJT) solar cells are one of the promising technologies for next-generation industrial high-efficiency cells, and many efforts in transferring this technology to high-volume manufacturing photovoltaic (PV) industry currently ongoing. Metallization is vital importance PV performance long-term reliability HJT cells. In review, we summarize develo...

Nigeria power system has been experiencing total or partial failures in recent times and voltage instability is a strong factor. The paper seeks to perform the stability analysis, based on static P-V plots, buses located around within South East zone of Nigeria. An injection group containing generators serve as source sink loads be monitored are created. assumed their min/max MW limits. load in...

Electric vehicle battery systems are made up of a variety different materials, each system contains hundreds batteries. There many parts that need to be connected in the system, and welding is often most effective reliable connection method. Laser has advantages non-contact, high energy density, accurate heat input control, easy automation, which considered ideal choice for electric manufacturi...

With the rapid development of new energy resources and diversified load, power network topology data have grown swiftly. To meet needs smart grid dispatching system, analysis to support marketing, distribution, other businesses in operation has become one bottlenecks grid. In grid, outgoing lines some generators are directly connected transformer, during busbar analysis, nodes only adjacent tra...

Currently, the photovoltaic industry is focusing on development of low-cost modules with increased efficiency by altering structure module. In this study, a PET electrode sheet module was fabricated using cell/module integration. The connecting (stacked busbar-less solar cell) to electrodes via lamination process. flat and grooved films. which A-stage paste applied, slipped disconnected. contra...

In this paper, the thermal management of a battery module with novel liquid-cooled shell structure is investigated under high charge/discharge rates and runaway conditions. The consists 4 × 5 cylindrical batteries embedded in aluminum multiple flow channels. suppression propagation were experimentally examined. temperature rise discharging process significantly greater than that charging phase....

Due to environmental problems in the world, need for electric vehicles is increasing. While transition Electric Vehicles continues, acceleration of this process plays an important role reducing problems. In order accelerate transition, charging units should become widespread and time be reduced. Higher power are needed reduce time. This where DC (Direct Current) fast come into play. study, vehi...

Silicon carbide (SiC) metal oxide semiconductor field effect transistors (MOSFETs) have many advantages compared to silicon (Si) MOSFETs: low drain-source resistance, high thermal conductivity, leakage current, and switching frequency. As a result, Si MOSFETs are replaced with SiC in industrial applications. However, there still not as modules customize for each application. To meet the high-po...
