20.500.12556/RUL-143799 Detailed luminescence modelling in high-efficiency solar cells for precise calibration of spatially resolved characterisation methods a bottom-up opto-electrical approach In the scope of solar cell characterisation, spatially resolved imaging (SRI) methods (EL, PL and LBIC) have long been a standard procedure for valuable in-depth evaluation and extraction of various spatially resolved material properties, especially those related to the electrical behaviour. While this extraction can be straightforward in the case of laterally homogeneous devices, the situation is vastly different when the structural features are laterally varying, such as in the case of interdigitated back contact (IBC) solar cells. We show that in the case of laterally varying devices inherent device optical properties play a far more important role in determining the measured profile in this case and may indeed overshadow any underlying electrical effects. We therefore propose and validate a methodology that couples SRI characterisation with advanced bottom-up simulation of IBC solar cells. The method fully accounts for lateral device variability and allows for accurate extraction of the underlying electrical phenomena. We demonstrate the applicability of the method on state-of-the-art high-efficiency IBC solar cells, and explain the key factors, which could lead to misinterpretation of the results obtained solely by SRI measurements. spatially resolved imaging electroluminescence optical simulation electrical simulation interdigitated back contact solar cells prostorska slikovna karakterizacija elektroluminiscenca optične simulacije električne simulacije sončne celice z izmenjujočimi kontakti na zadnji strani true false true Angleški jezik Slovenski jezik Članek v reviji 2023-01-12 11:12:13 2023-01-12 11:12:14 2023-01-13 04:03:47 0000-00-00 00:00:00 2022 0 0 11 str. art. 111990 Vol. 248 Dec. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.383.51 0927-0248 10.1016/j.solmat.2022.111990 121928195 1-s2.0-S092702482200407X-main.pdf 1-s2.0-S092702482200407X-main.pdf 1 9208CD3A5E6380A7AEDE254B75113617 471f2b2ffdbdd1aa0825d2d275afa527aabb777a9e3f174dfc0f6eb7db8cdd86 310a9e83-9262-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165737 https://www.sciencedirect.com/science/article/pii/S092702482200407X 0 5a65813d-9261-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165731 Fakulteta za elektrotehniko 0 0 0
