Plasmonic thin-film luminescent solar concentrators (PTLSCs) were prepared by coating polycarbonate substrates with fluorescent PMMA films doped with coumarin dyes, nanogold and nanosilver molecules. The study of the absorption and fluorescence spectra showed a highly efficient light harvesting...

The majority of the world's photovoltaic module production is shipped to developing countries for a variety of applications, such as rural electrification, telecommunication, water pumping, cathodic protection, street lighting, etc. This flow of imported modules and systems, coupled with the...

The paper presents the outcome of the powering of a conventional a.c. type water pump by photovoltaic (pv) solar modules which were 28 in number connected 7 in series giving a total of 4 parallel strings. An assesment of the system, which provides water to the University Mechanical Workshop and...

The aim of this article is to describe how closely PV grid-connected inverters (of around 5kW) operate at the actual maximum power point. These inverters could be installed at any low voltage, PV grid-connected systems. To carry this study out, twelve 50Hz single-phase inverters were selected...

A simulation of shading effects in arrays with different string configurations has been done. Simulation has been performed using as the basic unit the solar cell, modelled in direct bias by the conventional one exponential model, and in reverse bias by an equation previously validated in...
