Solar hybrids systems with TEG have been used to boost efficiencies of solar devices and at the same time improve the stability of performance. With recent advances in tracking system and high ZT TEG modules, solar power generation using TEG modules can be used to generate electricity and supplied to main grid. The advantage of these systems is double: - On the one hand, they allow cooling the photovoltaic cells (PV), which avoids the loss of electrical efficiency observed in the devices,On the other hand, recover this lost energy in the form of heat, and transform it into electrical energy thanks to the thermoelectric modules operating in Seebeck mode.
In addition, Thermoelectric devices are utilized in a wide variety of applications related to solid-state power generation and refrigeration. Over the past several years many new materials have been investigated for their use as thermoelectric materials. Despite the extensive investigations of new and traditional materials, there is still a need to investigate new classes of materials, with unique physical properties resulting in superior thermoelectric properties. This Special Topic Collection on Thermoelectric Materials provides a valuable forum where scientists and practitioners in the field share their most recent findings and reveal new advances to progress the fundamental understanding of thermoelectric materials and phenomena.
Modern technology depends on the ability to identify, control, and characterize defects in semiconductors. Native defects and impurities, whether they are beneficial or detrimental, play key roles in a range of materials. Applications include silicon chips, energy-efficient solar cells, light-emitting diodes and laser diodes, as well as emerging areas such as quantum computing and 2D materials. Advances in thin-film growth, microscopy, spectroscopy, and theory are leading to an unprecedented glimpse into atomic-level properties of point and line defects. The dramatic increase in knowledge gained by these studies is enabling engineers to incorporate new functionalities into semiconductor devices. This Special Topic on Defects in Semiconductors provides a valuable forum where researchers studying the fundamentals of defects in semiconductors can share their most recent and novel findings.
