20.500.12556/RUL-167572 From sunrise to sunset unraveling metastability in perovskite solar cells by coupled outdoor testing and energy yield modelling Perovskite-based solar cells exhibit peculiar outdoor performance which is not yet fully understood. The results of outdoor tests may contain hidden, but valuable information that cannot be fully extracted from measurements alone. One such phenomenon is the effect of nighttime degradation and the subsequent light-soaking recovery, which can take from a few hours in the morning up to the entire day. In this work, long-term outdoor monitoring is combined with energy yield modeling to qualitatively and quantitatively investigate the effect of light-soaking recovery in both single junction and tandem perovskite-based devices. Following the novel methodology presented in this study, it is observed that the light-soaking effect depends not only on the daily irradiation but also on the device temperature, and it can be described using a simple empirical formalism. Incorporating this dependency into the energy yield model results in an excellent agreement between the simulated and the measured outdoor data, which allows to perform long-term prediction studies. The model estimates that the light-soaking metastability effect decreases the attainable annual energy yield by up to ▫$\approx 5%$▫ for the studied single junction devices, and for tandems by up to ▫$\approx 3%$▫, depending on the geographical location, and even more for non-optimal device orientation. perovskite-based solar cells »light-soaking« effect realistic operating conditions outdoor monitoring energy yield modelling sončne celice na osnovi perovskitnih materialov »light-soaking« efekt realistični pogoji delovanja spremljanje delovanja sončnih celic na prostem modeliranje dolgoročnega energijskega donosa true false true Angleški jezik Slovenski jezik Članek v reviji 2025-02-28 09:55:06 2025-02-28 09:55:13 2025-03-01 04:14:49 0000-00-00 00:00:00 2024 0 0 10 str. iss. 29, art. 2304452 Vol. 14 Avg. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.383.51 1614-6840 10.1002/aenm.202304452 195661571 Advanced_Energy_Materials_-_2024_-_Remec_-_From_Sunrise_to_Sunset__Unraveling_Metastability_in_Perovskite_Solar_Cells_by_(1).pdf Advanced_Energy_Materials_-_2024_-_Remec_-_From_Sunrise_to_Sunset__Unraveling_Metastability_in_Perovskite_Solar_Cells_by_(1).pdf 1 5E27F71F99C4C662194C2F4F74959BE7 f8d3021e0385efed7be348893f451b8c099f16d4f5368cd495f8cb0f550ba2b6 ed3a00c7-f5b0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200221 https://onlinelibrary.wiley.com/doi/10.1002/aenm.202304452 1 ce6a7462-f5b0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200220 Fakulteta za elektrotehniko 0 0 0
