The vast and rising problems related with electric energy generation predominantly produced from fossil fuels, such as carbon dioxide emission and air pollution, demand a constant search for development of new renewable energy technologies. In this context, Energy Harvesting can be characterized as the harvesting and storage of portions of available energy in an environment [1]. A Thermoelectric Module...
Metal Oxide Varistors (MOVs) are employed as surge protective devices due to their capability of dissipating reasonably large values of surges. The pulse (life span) rating curves of a MOV provide the estimated life span of the device when exposed to multiple surges of the same magnitude. However, in reality, a lightning event (flash) consists of multiple current surges (strokes), with the first stroke...
Thermoelectric (TE) modules are solid-state devices that convert directly thermal energy in electrical energy. However, they can undergo performance degradation due to thermal cycling. In the present study, a control-based test platform that is capable to apply specific thermal cycling pattern at periodic intervals is presented in order to evaluate performance degradation that influence the TE module...
Terahertz (THz) spectroscopy has high sensitivity for the interaction between molecules and vibration of large molecules. Besides, it is well known that infrared (IR) spectroscopy can be used to detect the vibration of functional groups. Hence, the comparison of the conventional diagnosis method using IR spectroscopy and THz spectroscopy is expected for more potential diagnosis. In this study, the...
Multicrystalline solar grade silicon solar cells from metallurgical process route and small Cz-Si test ingots have been investigated to further understand the impact of compensation and related reduced majority carrier mobilities. A possible PB complex which may prevent BO2i complex formation has been discussed recently by different research groups in several contributions. Our low temperature PL...
