This paper introduces the simple method of the mathematical modeling and simulation of current-voltage characteristics for photovoltaic panel. The aim of this modeling is to simply the nonlinear I-V model of photovoltaic panel to easily apply the model to the circuit simulators such as SPICE. So this paper is finding the parameters for the nonlinear I-V equations based on only the data such as ...

This paper presents the characterization and analysis of a 16.8%-efficient 18 um silicon solar cell on steel substrate. Photoluminescence (PL) is used to monitor the solar cell’s fabrication step by step, and a correlation between PL intensity and implied open circuit voltage is established. PL images yield spatially resolved maps of key electrical parameters such as dark reverse saturation cur...

A  commercial  Ti-Nanoxide  was  deposited  on  In-doped  SnO2 (ITO) polymer  substrates by  tape casting  technique with different thicknesses  (7,  14  and  36μm)  to  be  used  as  photoelectrode  in flexible  dye-sensitized  solar  cells  (DSSCs).  Ruthenium  dye  was adsorbed on each TiO2 film for 24 h. The resulting photoelectrodes were used to form flexible DSSCs in combination with...

Two organic compounds (SC-23=(E)-2-Cyano-3-(2,3-dimethoxyphenyl) acrylic acid and SC-25=(E)-2-Cyano-3-(2,5-dimethoxyphenyl) acrylic acid) involving methoxy groups as the electron donor and cyanoacrylic acid group as the electron acceptor have been investigated for dye sensitized solar cells. They shows a short-circuit current density (Jsc) of 2.08 and 1.81 mA cm-2, an open circuit voltage (Voc)...

Different layered ZnO/MEH:PPV composite solar cells have been fabricated to assess the role of the ZnO backing layer on the open circuit voltage of nanowire composite solar cells. Comparisons between cells using a ZnO layer prepared by spray pyrolysis and by sputtering and oxidising a Zn layer are compared. Cells with a sputtered Zn layer which is then oxidised show a significantly improved ope...

Induction motor is the most popular load in the industry, it is very important to study about the effects of voltage quality on induction motor performance. One of the most important voltage quality problems in power system is voltage unbalance. This paper evaluates and compares two methods including finite element method (FEM) and equivalent electrical circuit simulation for investigation ...
