Abstract

Today, from powering a satellite and telescopes in space, to lighting up a solar-powered traffic light on a street; an application of solar energy has rapidly increased and growing over the time. Solar energy is among the renewable energy that important as an alternative to an extinction of fossil fuel generated-electricity like a coal, oil and nuclear energy. It is very significant to comprehend solar cell characteristics in order to study the performance of solar cells. In the real world, manufacturer of solar cell does not include an equivalent circuit model generally or specifically. The circuit is important as it includes the dynamic impedances of solar cells, which are essential in determining the dynamic performance of solar cells. Therefore, with this experiment we can measure and extract the parameter of the circuit using a technique called Frequency Response Analysis (FRA). The main objective for this thesis is to study the function of the FRA device, the Frequency Response Analyzer Bode 100 on a solar cell. Moreover, this thesis will analyze an experimental test for Bode 100 to a solar cell. Then, to study the dynamic impedance of solar cell relationship between different types of solar cells and on different range of DC bias injected to solar cells. The experiment conducted, limit the types of PV modules that tested to two types only, which are 5.5 V 0.85 W poly-crystalline silicon solar cell and 5 V 0.5 W mono-crystalline silicon solar cell. The experiment also uses two amount of different DC bias injected to the solar cell; which are 6 V and 12 V. After design and development of experimental setup takes place, all the data will be capture using software called Bode Analyzer Suite. A frequency injection process runs over the solar cell will produce responses that visualize the pattern of the dynamic impedances. Hence, all the result of the measurement is presented clearly. The result is analyzed through signal processing techniques and comparison techniques. Finally, at the end of this project, dynamic impedances of solar cells have been developed.
