摘要

In the present work we compare the indoor and outdoor performance of a set of CIS medium/large-areamodules coming from different industrial/pilot productions. By comparing indoor to outdoor data we observe that themaximum power Pmax (Voc, and FF) measured indoors by our flashed solar simulator is systematically lower than thepower measured outdoors. In the best cases the indoor measurement underestimates the P_(max) by only 2.5%, in theworst case by more than 11%. Furthermore, for some devices we separately investigate the effects which lead to adiscrepancy of outdoor to indoor data: (a) material’s related quasi-stable effects, usually related to light soaking; (b)measurement related sweep-time effects: the influence of the duration of the IV scan when using a pulsed solarsimulator; and by (c) what we define the pre-measurement state: the state in which the device is kept, sometimes for avery short interval (some ms), before the measurement. Moreover, we demonstrate that our pre-conditioningprocedure (20 minutes of LS at 800 W/m~2, T≈40°C and with a subsequent period of 15-30 minutes for adaptation toambient conditions) significantly reduces the discrepancies between indoor and outdoor measurements for all thedevices under test giving a more precise estimation of the outdoor performance of the module.
