Photovoltaic cells, as the primary part of a solar photovoltaic system, are a nonlinear DC power supply related to multiple parameters. The demand of increasing the generating efficiency of photovoltaic cells requires having a good understanding of their electrical characteristics. In this study, the mathematical and physical model of the photovoltaic cells was built by the means of Matlab and ...

In recent years, energy production by renewable sources is becoming very important, and photovoltaic (PV) energy has became one of the main renewable sources that is widely available and easily exploitable. In this context, it is necessary to find correct tools to optimize the energy production by PV plants. In this paper, by analyzing available solar irradiance data, an analytical expression f...

The development of photovoltaic (PV) energy throughout the world this last decade has brought to light the presence of module mismatch losses in most PV applications. Such power losses, mainly occasioned by partial shading of arrays and differences in PV modules, can be reduced by changing module interconnections of a solar array. This paper presents a novel method to forecast existing PV array...

We report the results of production start-up efforts at the 2MW Sovlux photovoltaic production line. Triple-junction solar cells with higher than 10% initial effXency were produced in this production line with subcell yield up to 96%. The production process demonstrated high reproducibility and consistency from run to run. 2 t? and 4 @ modules assembled in sovlux plant using these solar cell ma...

In this work, we present a new algorithm for detecting faults in grid connected photovoltaic (GCPV) plant. There are few instances of statistical tools being deployed in the analysis of PV measured data. The main focus of this paper is, therefore, to outline a PV fault detection algorithm that can diagnose faults on the DC-side of the examined GCPV system based on the t-test statistical analysi...

We present new services, developed also under the GMES ENDORSE (ENergy DOwnstream SErvices) project, for the performance analysis and the support in the planning of solar plants (photovoltaic, CSP, CPV) that combine a detailed model of each part of the plant (solar field, thermal storage system, electrical power system and inverters) and the near real-time remote sensing of the global (or direc...

Arising applications of ferroelectric materials in photovoltaic devices" The ferroelectric-photovoltaic (FE-PV) device, in which a homogeneous ferroelectric material is used as a light absorbing layer, has been investigated during the past several decades with numerous ferroelectric oxides. The FE-PV effect is distinctly different from the typical photovoltaic (PV) effect in semiconductor p–n j...

Photovoltaic (PV) power generation has an important role to play due to the fact that it is a green source. The only emissions associated with PV power generation are those from the production of its components. Increasing the efficiency in PV plants so the power generated increases is a key aspect, as it will increase the incomes, reducing consequently the cost of the power generated so it wil...

Variability of solar power is a key driver in increasing the cost of integrating solar power into the electric grid because additional system resources are required to maintain the grid’s reliability. In this study, we characterize the variability in power output of six photovoltaic plants in the USA and Canada with a total installed capacity of 195MW (AC); it is based on minute-averaged data f...

Global energy demand is increasing as greenhouse gas driven climate change progresses, making renewable energy sources critical to future sustainable power provision. Land-based wind and solar electricity generation technologies are rapidly expanding, yet our understanding of their operational effects on biological carbon cycling in hosting ecosystems is limited. Wind turbines and photovoltaic ...
