Papers by Keyword: Recombination Centre Distribution

Abstract: The paper refers about a possibility to check recombination rate distribution over the area of power (large-area) solar cells from measured values of open circuit voltage V_OC using local irradiation by monochromatic light of different wavelengths (LBIV . Light Beam Initiated Voltage). The method can give information both about recombination centres distribution in large-area solar cells and surface recombination rate at the antireflection coating. From V_OC distribution, also position and extent of local defects can also be determined. The method can be used to investigate the influence of technology on characteristics of solar cells as an in-process checking with the aim of increasing efficiency and reliability of solar cells.

Abstract: The paper refers about problems connected with development of course on photovoltaics in the bachelor level of the study. Curricula of a course on photovoltaic systems performed at the Czech Technical University in Prague, Faculty of Electrical Engineering is presented. In the contribution is described the present state and compared with history and the project of the further development. Orientation of laboratory exercises towards applications has been supposed.
