20.500.12556/RUL-134034 Are perovskite solar cell potential-induced degradation proof? Potential induced degradation (PID) is a solar cell related degradation mechanism due to high potential difference in a photovoltaic (PV) module between the solar cells and its grounded frame. This type of degradation is well known for silicon PV, however, for perovskites it has not been thoroughly researched yet. Here, we investigate the PID of perovskite solar cells for bias voltages of ±500 V, half of the currently used system voltage, and ±1000 V with regular I-V and EL measurements during the test. Our devices show a high PID resistance under applied bias of ±500 V, far exceeding the recommended guidelines for silicon PV. However, for the bias voltage of -1000 V a rapid degradation was observed due to the ingress of sodium ions from the glass substrate as confirmed by the ToF-SIMS measurements of spatial and depth distribution of elements in solar cells. Positively biased devices show no degradation due to high voltage exposure. These results show promising signs that perovskite solar cells are PID proof for current PV system designs. perovskite solar cells potential-induced degradation stability field operation perovskitne sončne celice napetostno vzbujena degradacija stabilnost zunanje delovanje true false false Angleški jezik Slovenski jezik Neznano 2021-12-22 11:42:29 2021-12-22 11:42:29 2022-09-13 03:52:57 0000-00-00 00:00:00 2021 0 0 Str. 1-10 2100815 [in press 2021] 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-12-11 2022-12-11 621.383.51:53 2367-198X 10.1002/solr.202100815 90437635 RAZ_Brecl_Kristijan_2021.pdf RAZ_Brecl_Kristijan_2021.pdf 1 1703DFF61A66546FA1BC7449C62FF6F4 ecaae37500afb02da79a833d3dae74a44df638b1d28279043ae95bbd15b99b14 c4a0f962-6314-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152336 Fakulteta za elektrotehniko 0 0 0
