Performance analysis of a multi crystalline Si photovoltaic module under Mugla climatic conditions in Turkey
(Pergamon-Elsevier Science Ltd, 2013)
Commercially available, a multi crystalline silicon (mc-Si) photovoltaic (PV) module has been monitored outdoors under Mugla climatic conditions in Turkey. Electricity yield of this module is calculated from the uninterruptible ...
Performance comparison of a double-axis sun tracking versus fixed PV system
(Pergamon-Elsevier Science Ltd, 2012)
In the present study, performance results of two double axis sun tracking photovoltaic (PV) systems are analyzed after one year of operation. Two identical 7.9 kWp PV systems with the same modules and inverters were installed ...
Monitoring the performance of single and triple junction amorphous silicon modules in two building integrated photovoltaic (BIPV) installations
(Elsevier Sci Ltd, 2013)
Mugla is located in south west Turkey at 37 degrees 13'N latitude and 28 degrees 36'E longitude with yearly sum of horizontal global irradiation exceeding 1700 kWh per square meter. Mugla has a Mediterranean Climate which ...
Extended investigation of intermartensitic transitions in Ni-Mn-Ga magnetic shape memory alloys: A detailed phase diagram determination
(Amer Inst Physics, 2013)
Martensitic transitions in shape memory Ni-Mn-Ga Heusler alloys take place between a high temperature austenite and a low temperature martensite phase. However, intermartensitic transformations have also been encountered ...
Viscoelasticity, dielectric anisotropy, and birefringence in the nematic phase of three four-ring bent-core liquid crystals with an L-shaped molecular frame
(Royal Soc Chemistry, 2013)
Molecular shape is an important factor in determining the material properties of thermotropic liquid crystals (LCs). We synthesized and investigated several LC compounds formed by asymmetrically bent molecules with a rigid ...
The effect of aging on the dark conductivity and noise in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)
Aging hydrogenated microcrystalline silicon in air is found to affect both the dark conductivity and the 1/f noise. For a sample with a crystalline volume fraction of 0.39, the conductivity decreased by three orders of ...
Investigation of light induced degradation in hydrogenated amorphous silicon-germanium alloy thin films using temperature dependent photoconductivity
(Wiley-V C H Verlag Gmbh, 2010)
Light induced degradation of undoped hydrogenated amorphous silicon-germanium (a-SiGe:H) alloys with different Ge contents has been investigated using intensity and temperature dependence of photoconductivity between 78K ...
Solvent washing with toluene enhances efficiency and increases reproducibility in perovskite solar cells
(Royal Soc Chemistry, 2016)
We report a simple process for reproducibly fabricating perovskite solar cells. We emphasize that the solvent washing technique is the most practical method for successful uniform crystallization so it facilitates highly ...
Magnetic properties of La0.65Ca0.30Pb0.05Mn0.9B0.1O3 (B = Co, Ni, Cu and Zn)
(Elsevier Science Sa, 2015)
The La0.65Ca0.30Pb0.05Mn0.9B0.1O3 (A = Co, Ni, Cu and Zn) manganites have been prepared via sol-gel method and sintered at 1100 degrees C for 24 h. The aim of the study was to investigate B-site cation doping effects on ...
Instability effects in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)
Instability effects on the dark conductivity (sigma(Dark)) and photoconductivity (sigma(photo)) of microcrystalline silicon films with different microstructures deposited on smooth and rough substrates, after exposure to ...
