也常被称为 “标板”,是封装完成的标准化光伏组件样品,主要用于光伏组件 IV 特性测试等场景的设备校准。按校准等级可分为一级和二级标准光伏组件,一级以标准太阳电池为基准校准,二级则以一级标准光伏组件为基准标定,对应量值传递链中的工作标准等级。在 IV 测试中,通过对比该样品的已知输出值与测试设备读数,能校正仪器误差、消除环境差异影响,同时符合 IEC 60904 系列等行业标准对测试可靠性和可追溯性的要求。
The World PV Scale Standard is recognized as an international standard for calibrating reference cells used in the characterization of solar cells and modules. To comply with the WPVS standard and the requirements of IEC 60904-2, reference cells must meet a wide range of optical, electrical, thermal and mechanical criteria and be calibrated and recalibrated in accordance with international standards.
The CalLab provides WPVS reference cells for primary or secondary calibration which fully meet these specifications. WPVS reference cells from the CalLab are available with or without calibration in accordance with IEC.
Interested customers with professional experience in the photovoltaic field can use Fraunhofer ISE’s indoor and outdoor reference cells, which were originally developed for the institute’s own use. This enables a high level of measurement precision to be achieved for the first time at locations other than specialized calibration laboratories.
