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...

To model the active layer in the hetero-junction solar cells, the C60, C70, PC60BM, PCBDAN fullerenes as acceptor, and (OS)n=1) oligoselenophenes as donor were considered. The (OS)n=14/C60, (OS)n=14/C70, (OS)n=14/PC60BM, and (OS)n=14/PCBDAN blends as a model of the active layer in the BHJ solar cell were chosen, and the optoelectronic properties were studied. The calculated efficiency of these ...

This work presents a new type of transparent conductive adhesive and its electrical optical properties with regards to an application in III–V on Silicon tandem solar cells. The developed is based doped ZnO deposited by spray coating. interconnection the two sub-cells identified as one major challenges due reflectance at bond possible approaches reduce are investigated simulations. Regarding in...

New Schiff-base compound (E)-4-methoxy-N-(4-hydroxybenzylidene) aniline has been synthesized from the reaction of 4-hydroxybenzaldehyde with 4-methoxyaniline in methanol at 50ºC, and has been characterized by using elemental analysis and FT-IR spectroscopy. The crystal structure of the title compound has been determined by single crystal X-ray diffraction study. The title compound crystallizes ...

The need for a cleaner environment and the continuous increase in power demands makes decentralized renewable energy production, like solar and wind more and more interesting. Decentralized energy production using solar energy could be a solution for balancing the continuously-increasing power demands. This continuously increasing consumption overloads the distribution grids as well as the powe...

statement of problem: recently, it has been proposed that different adhesive materials can be used for direct pulp capping. previous studies have demonstrated that multi steps dentin adhesives could form reparative dentin similar to calcium hydroxide (ch). purpose: the aim of this study was to evaluate the histological pulp response of ninety mechanically exposed cat pulps to two adhesive resin...

Today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. One of the almost endless and pure energy which have been paid attention over the years is the solar energy. Solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. Significant improvement has been made...

 Researchers in the field of simulation have been mainly interested in the question of how to increase the efficiency of solar cells. Therefore this study aimed to investigate CdS/CdTe solar cells by applying AMPS-1D software. The impact of semiconductor layers thickness on the output parameters of the CdS/CdTe solar cell is being analyzed and studied carefully, for example, fill factor, effici...
