碩士 === 中原大學 === 電子工程研究所 === 107 === In order to make CPV (Concentrated Photovoltaic) technology a major trend in solar power generation, it is necessary to widely observe the photoelectric characteristics of high-concentration modules through outdoor observation data. The high concentrating module is a high-concentration characteristic of a three-junction (Ge/GaAs/InGaP) solar cell plus a Fresnel lens, and the concentrating magnification is more than 1100 times. The dual-axis chasing system is equipped to fully utilize the advantages of high concentrating light. Periodically measure the photoelectric parameters provided by the module under the direct standard spectrum of AM1.5D, and compare the external environmental factors that affect the performance of the module, such as DNI (direct normal illumination), module temperature, ambient temperature, etc. The observation data of this study were sampled at the Nuclear Energy Research Institute in Longtan District, Taoyuan City. The observation period was from August 2017 to July 2018 for a total of one year. Further, through the EQE (external quantum benefit) values of different spectral segments, the SMR (spectral mismatch ratio) between the TOP layer and the MID layer and the standard spectrum is obtained, and then the correlation between the SMR and the module photoelectric characteristics is discussed, thereby Forecast and analysis.
