Solar power represents a vast resource which could, in principle, meet the world's needs for clean power generation. Recent growth in the use of photovoltaic (PV) technology has demonstrated the potential of solar power to deliver on a large scale. Whilst the dominant PV technology is based on crystalline silicon, a wide variety of alternative PV materials and device concepts have been explored...

The influence of electromagnetic scattering by Au and silica nanoparticles placed atop silicon photovoltaic devices on absorption and photocurrent generation has been investigated. The nanoparticles produce substantial increases in power transmission into the semiconductor and consequently photocurrent response from 500 to 1000 nm. Increases in power conversion efficiency under simulated solar ...

A high density of Photovoltaic generation can lead to problems in low voltage grids. This paper addresses the problem by actively and anticipatory using the load shifting and load influencing potentials in households. The goal is to achieve a local generation/load balance. To analyse the potential in Austrian households, a model settlement is generated, which represents Austria as a small villa...

A hybrid molecular photovoltaic system, based on fullerene C(60) and lutein (a natural photosynthetic carotenoid pigment) that are assembled in a phospholipid/alkanethiol bilayer matrix, is described here. The assembly and photoconversion behaviors of such a system were studied by UV-vis spectroscopy, cyclic voltammetry, impedance spectroscopy, photoelectrochemical action spectroscopy, and phot...

In this paper an optimal placement of photovoltaic systems (PV) as a source of active and reactive power in radial distribution networks is considered. The objective function of this problem is minimizing system losses and improving voltage profile. Genetic Algorithm (GA) implemented for this purpose. Photovoltaic solar systems can be used as STATCOM for voltage regulation and power factor corr...

The EU climate and energy targets and the decreasing costs have been leading to a growing utilization of solar photovoltaic generation in residential buildings. However, even in buildings with the same level of yearly generation and consumption the mismatch between the demand and the photovoltaic generation profiles leads to high power flows between the household and the grid, which is an ineff...

Solar photovoltaic (SPV) has emerged as one of the major renewable source of electricity generation. Solar electricity is more expensive than that produced by traditional sources. But over the past two decades, the cost gap has been closing. Solar photovoltaic (SPV) technology has emerged as a useful power source of applications such as lightning, meeting the electricity needs of villages, hosp...

Triplet-exciton formation through intersystem crossing of photogenerated singlet excitons in fullerene acceptors can compete with charge generation in organic photovoltaic diodes. This article reports the intersystem crossing timescale (τISC ) of the most commonly used fullerene acceptors, PC60 BM and PC70 BM, in solutions and in spin-coated films. These times are on the nanosecond timescale, a...
