摘要：
为实现太阳电池光电参数测量条件的一致性，进而保证测量数据的准确性、实验室间测量数据比对及互认的公正性，该文通过对太阳电池的开路电压温度修正、短路电流温度修正、太阳辐照强度修正等量值传递技术的研究，完成参考太阳电池在标准状态（STC）下的量值传递到室外自然环境下的太阳电池组件，实现对非标准条件下太阳电池组件光电参数的STC修正。太阳电池组件修正后的开路电压值、短路电流值与STC条件下的开路电压值、短路电流值相对偏差分别为–0.95%、0.58%。该量值传递技术及其方法为非STC条件下太阳电池组件光电参数实验室间比对及互认提供可能。

Abstract: In order to achieve the consistency of measurement conditions for photoelectric parameters of solar cells and ensure the accuracy of the measurement data, the inter-laboratory measurement data comparison and the fairness of mutual recognition, this paper carried out the research of transfer technology of values of open-circuit voltage temperature correction, short-circuit current temperature correction and solar irradiation intensity correction for solar cells. The value of reference solar cells in standard state (STC) was successfully transferred to solar module in outdoor natural environment, realized STC correction of photoelectric parameters of solar modules under non-standard conditions. The relative deviation of solar module's open circuit voltage value and short circuit current value between the corrected condition and the STC condition is -0.95% and 0.58%, respectively. The value transfer technology provides the possibility of inter-laboratory comparison and mutual recognition of solar module photoelectric parameters under non-STC conditions.
