Concentrating photovoltaic thermal (CPVT) technology has the potential to support industrial sector with renewable electricity and heat simultaneously. The implementation of spectral splitting emerges as a possible approach significantly increase conversion efficiency, furthermore, hurdle fundamental discrepancy CPVT systems, that electrical receiver part have opposing temperature requirements....

Small-scale photovoltaic-powered reverse osmosis (PVRO) desalination plants can provide fresh water to remote communities that do not have sufficient natural sources. The technical feasibility of such systems is well-established and the economics for specific locations have been addressed. Recently, generalized methods to evaluate their economic feasibility have been proposed. They show that th...

In this paper, we discuss two new paradigms for enabling costeffective III-V solar cell photovoltaics using (i) our novel layer transfer technology, called controlled spalling and (ii) new solar cell device structures. First, we present the application of the controlled spalling for making high-efficiency thin-film multijunction solar cells. Finally, a novel GaAs heterojunction solar cell struc...

the increase of cell temperature with increased irradiance is probably the mostsignificant disadvantage of using photovoltaic modules equipped with booster reflectors. the aimof this study is to investigate the possibility of improving the performance of a photovoltaic waterpumping system by using a booster reflector and to keep the temperature of pv panels at a lowlevel by cooling pv panels wi...

The effective management of technology and new product development in a high technology small to medium enterprise associated with a large corporation with specific reference to the development of solar photovoltaic water pumps is investigated in this study. Innovative product and the development thereof have already become this century's battleground. The availability of information to all and...

We consider a 3-brane embedded in a warped 5-dimensional background with a dilaton and a Kalb-Ramond 2-form. We show that it is possible to find static solutions of the form of charged dS/AdS-like black hole with horizon which could have a negative mass parameter. The motion of the 3-brane in this bulk generates an effective 4dimensional bouncing cosmology induced by the negative dark radiation...
