Solar energy is currently available for development and utilization of green alternative energy in a more potential for development. The development of solar energy is mainly based on photoelectric conversion, and the research is committed to improving the solar energy materials to enhance its photocurrent, by virtue of this purpose to enhance the efficiency of solar power generation system. However, regardless of how the performance of solar cell materials to enhance, its biggest drawback is the power generation efficiency by the impact of sunshine intensity, and since the beginning are not effective to improve the results. Therefore, the laboratory solar energy conversion circuit, is designed a storage circuit in the shade, cloudy, rainy days can still continue to store energy, so that the back-end Inverter circuit to normal action, in order to enhance the overall efficiency of solar energy.”
