This Paper presents Maximum Power Point Tracking (MPPT) of Photovoltaic Array under partial shading condition. The power available at the output of photovoltaic cells keeps changing with solar insolation and ambient temperature because photovoltaic cells exhibit a nonlinear current voltage characteristic. A good number of publications report on different MPPT techniques for PV system most of th...

Solar energy offers a pollution free and sustainable means of harvesting energy directly from the sun. Considerable effort has been directed toward maximizing the efficiency of end-to-end solar systems, including the design of photovoltaic cells [15, 26], engineering new photovoltaic architectures and materials [24], and solar tracking systems [4]. Solar tracking is especially important for max...

A one-dimensional mathematical model of the liquid-junction photovoltaic cell was coupled with primary resistance calculations to predict the optimal performance of three cell configurations. Two cells are considered in which the semiconductor is i l luminated from the electrolyte side and one in which the semiconductor is i l luminated from the current-collector side. An economic analysis is p...

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 elec...

with the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. the novel concept of photovoltaic powered ...

The development of flexible organic photovoltaic solar cells, using an optically transparent substrate material and organic semiconductor materials, has been widely utilized by the electronic industry when producing new technological products. The flexible organic photovoltaic solar cells are the base Poly (3,4ethylenedioxythiophene), PEDOT, Poly(3-hexyl thiophene, P3HT, Phenyl-C61-butyric acid...
