In the perspective of the Net Zero Energy Buildings as specified in the EPBD 2010/31/EU, we propose the concept and design of a modular unglazed solar thermal (UST) façade component for facilitating the installation of active solar façades. The renovation of existing buildings offers an opportunity to improve the energy efficiency when using such a system and a novel design methodology tackled ...

The current research seeks to maintain high photovoltaic (PV) efficiency and increased operating PV life by maintaining them at a lower temperature. Solid-liquid phase change materials (PCM) are integrated into PV panels to absorb excess heat by latent heat absorption mechanism and regulate PV temperature. Electrical and thermal energy efficiency analysis of PV-PCM systems is conducted to evalu...

Non-uniform irradiance patterns over Multi-Junction Cells gives rise to power losses, especially when considering spectral irradiance distributions over different junctions. Thermal effects on Silicone-on-Glass lenses affect spectral irradiance distributions. A new Photovoltaic Concentrator (CPV), formed by nine optical channels, each one with a Köhler configuration, has been designed to overco...

A hybrid system is described that combines the features of two solar technologies – photo-voltaic conversion to electricity (PV) and thermal conversion to heat and finally to electric energy for battery usage. Under the condition of the same output power of photovoltaic system, using low cost superiority of the high concentrator material in place of the expensive solar cell to reduce the compre...

As device dimensions are scaled down, single event transients (SET) are increasingly affecting the reliability of integrated circuits. An SET is a transient voltage perturbation caused by an energetic particle strike at the semiconductor. This work studies the applicability of bulk built in current sensors (bulk-BICS) for SET detection in deep-submicron technologies. The bulk-BICS detects the t...

The objective of this study is to improve the performance a hybrid photovoltaic/thermal (PV/T) air heater incorporating thermal energy storage system (TESS) that uses paraffin and has metallic mesh layers. In experimental part research, three different pilot-scale PV/Ts have been designed, manufactured, experimentally investigated. first was structured as conventional PV/T, while second (PVT/TE...

This paper studied the performance of a compressor-assisted thermochemical sorption energy storage (CATSES) system with solar photovoltaic-thermal collector (PV/T) to support domestic space and hot water heating. The heat from PV/T drives endothermic desorption, whilst electricity powers compressor assist low-temperature desorption. main aim this study was demonstrate that integrated can flexib...

Emerging self powered systems challenge and dictate the direction of research in energy harvesting (EH). State of the art in energy harvesting is being applied in various fields using different single energy sources or a combination of two or more sources. In certain applications like smart packaging, radio frequency (RF) is the preferred method to power the electronics while for smart building...
