摘要

In the present work we compare outdoor and indoor performance measurements of two sets of thin film large-area (> 1m~2) modules: 1) single-junction a-Si and 2) tandem a-Si/μc-Si. For the single-junction device, the indoor measurement with a pulsed solar simulator - after mismatch factor (MMF) correction - underestimates the P_(max) by 3.3% compared to the outdoor measured P_(max) (also MMF corrected), whereas for the tandem device the indoor measurements overestimates the P_(max) by 4.9%. For the single-junction modules the discrepancy is within the measurement uncertainty of our measurement set-ups, whereas for tandem devices the discrepancy between indoor and outdoor slightly exceeds the calculated measurement uncertainty valid for standard devices. However, our calculation of measurement uncertainties did neither take sweep speed effects into account nor did it consider the uncertainties arising in the special case of tandem devices, due to current mismatch. Sweep-time measurements show the influence of the IV scan speed and direction on the measured FF, and therefore on P_(max). According to our results flashers with a pulse duration of 1.5 ms are not sufficient and at least 10 ms should be used to test these devices in a laboratory. The discrepancies in the measurement of short circuit current (I_(sc)) for both set of devices may originate from uncertainties in the calculation of the MMF correction. Moreover, for tandem devices the spectral mismatch correction is not yet standardized, but in one approach each junction is treated as a separate device. Although a larger temperature range is accepted for the outdoor performance measurement a relatively good match between indoor and outdoor measurements is obtained for V_(oc). These results will form the basis for the performance measurement of large-area multi-junction devices at ESTI and the development of a calibration procedure for tandem devices.
