ВЛИЯНИЕ ИНТЕРФЕРЕНЦИИ НА ЭФФЕКТИВНОСТЬ ИНВЕРТИРОВАННЫХ ФОТОВОЛЬТАИЧЕСКИХ ЯЧЕЕК

An expression and the analysis of the external quantum efficiency (EQE) for for inverted flat heterojunction based on copper phthalocyanine and fullerene. The analysis of the external quantum efficiency of photovoltaic cells has shown that the averaging EQE over the spectrum of solar radiation for the inverted cell interference redistribution has little effect on the EQE and optimization of cells to the thickness of its layers does not lead to a significant increase in quantum efficiency.Получено выражение и выполнен анализ внешней квантовой эффективности (EQE) для инвертированных фотовольтаических ячеек с плоским гетеропереходом на основе фталоцианина меди и фуллерена с одним и двумя прозрачными электродами. Показано, что при усреднении EQE по спектру солнечного излучения для инвертированных ячеек интерференционное перераспределение оказывает слабое влияние на EQE и оптимизация ячеек по толщинам составляющих ее слоев не приводит к значительному повышению квантовой эффективности

Growth of few-wall carbon nanotubes with narrow diameter distribution over Fe-Mo-MgO catalyst by methane/acetylene catalytic decomposition

Few-wall carbon nanotubes were synthesized by methane/acetylene decomposition over bimetallic Fe-Mo catalyst with MgO (1:8:40) support at the temperature of 900°C. No calcinations and reduction pretreatments were applied to the catalytic powder. The transmission electron microscopy investigation showed that the synthesized carbon nanotubes [CNTs] have high purity and narrow diameter distribution. Raman spectrum showed that the ratio of G to D band line intensities of IG/ID is approximately 10, and the peaks in the low frequency range were attributed to the radial breathing mode corresponding to the nanotubes of small diameters. Thermogravimetric analysis data indicated no amorphous carbon phases. Experiments conducted at higher gas pressures showed the increase of CNT yield up to 83%. Mössbauer spectroscopy, magnetization measurements, X-ray diffraction, high-resolution transmission electron microscopy, and electron diffraction were employed to evaluate the nature of catalyst particles
