| Zusammenfassung | To minimize the measurement uncertainty of indoor measurements of PV module efficiency, the accurate determination of the spatial distribution of irradiation is essential. The international standard IEC 60904-9 (2007) describes procedures to classify the basic optical properties of solar simulators, including the measurement of the spatial distribution of irradiation [1]. The development and characterization of high quality light sources for solar simulation with lowest non-uniformity requires adequate means and methods to determine repeatable and reliable values of the irradiance non-uniformity. We present different methods for measuring pulsed solar simulators irradiance uniformity on PV module scale and discuss the results obtained with the different methods. Herein, special emphasis is laid on the characterization and evaluation of the measurement equipment used and the impact on measurement uncertainty for the irradiance non-uniformity. According to our observations, it is required to consider local temporal stability of the irradiance distribution for precise and comparable measurements. In our investigation, we are also involving optical properties of typical crystalline silicon c-Si device under test modules to be part of the uncertainty analysis of non-uniformity measurements. We discuss the requirements for equipment and methods to report reliable values on solar simulators irradiance nonuniformity below 1 % and the corresponding measurement uncertainty affecting PV module efficiency measurements. |
