This paper conducted an economic analysis of the viability of five solar photovoltaic installations in County Tipperary, Ireland. Economic barriers along with policy recommendations are also discussed in detail in order to incentivise solar photovoltaics installations in Ireland. Using costings, solar photovoltaic energy output data and solar radiation data it is also investigated how Irish fin...

In this paper, a maximum power point tracker method using sliding mode control for a photovoltaic (PV) system is presented. The system includes a photovoltaic array, a DC/DC converter and a DC/AC inverter connected to a load. The designed control regulates the converter output voltage and it maximizes the power generated by the photovoltaic array. To obtain it, the sliding surface used to contr...

Low cost, high efficiency photovoltaic can help accelerate the adoption of solar energy. Using tapered indium phosphide nanopillars grown on a silicon substrate, we demonstrate a single nanopillar photovoltaic exhibiting illumination angle insensitive response. The photovoltaic employs a novel regrown core-shell p-i-n junction to improve device performance by eliminating shunt current paths, re...

Standalone photovoltaic system requires a proper battery charge controller. The main disadvantage of photovoltaic system is its variations in output voltage. Therefore to obtain a stable voltage from solar panels, DCDC converters are used. This paper explains the use of cuk converter with MPPT technique in a photovoltaic system. The MPPT is implemented by incremental conductance algorithm with ...

In recent years, FinFET transistors have received much interest thanks to the better immunity to short-cannel effects [1]. DC characteristics of FinFETs at high temperature were recently reported in [2]. RF characteristics of Bulk Si MOSFETs measured at low temperature (77K) have been presented in a few papers [3]-[4]. To the knowledge of the authors, the DC and RF characteristics, over a wide ...

The effective actions of a scalar and massless spin-half field are determined as functions of the deformation of a symmetrically squashed three-sphere. The extreme oblate case is particularly examined as per-tinant to a high temperature statistical mechanical interpretation that may be relevant for the holographic principle. Interpreting the squashing parameter as a temperature, we find that th...

We describe a systematic and efficient method of determining pseudo-atom positions and potentials for use in nanostructure calculations based on bulk empirical pseudopotentials (EPMs). Given a bulk EPM for binary semiconductor X, we produce parameters for pseudo-atoms necessary to passivate a nanostructure of X in preparation for quantum mechanical electronic structure calculations. These passi...

We propose a method for estimating the matter content of quasar jets which exhibit Chandra detected knots in their kpc scale jets. The method relies on measuring the component of the Cosmic Microwave Background (CMB) radiation that is bulk-Comptonized (BC) by the cold electrons in the relativistically flowing jet. We apply our method to PKS 0637 – 752, a superluminal quasar with an one – sided ...

Ti-based bulk metallic glasses (BMGs) are very attractive for applications because of their excellent properties such as high specific strength and high corrosion resistance. In this paper, we briefly review the current status of the research and development of Ti-based bulk metallic glasses. Emphasis is laid on glass-forming ability, mechanical properties, corrosion resistance, and biocompatib...

A solar photovoltaic system produces electricity by converting energy from the sun. By the end of 2016, the global installed solar photovoltaic capacity reached 305 GW. Its growth is impressive in the last years; in fact, it was only equal to 41 GW in 2010. However, Europe has installed only 6.9 GW in 2016 (−1.7 GW in comparison to previous year) and this annual power installed is equal to 9% o...
