20.500.12556/RUL-164941 Performance of triple-cation perovskite solar cells under different indoor operating conditions We systematically analyze triple-cation perovskite solar cells for indoor applications. A large number of devices with different bandgaps from 1.6 to 1.77 eV were fabricated, and their performance under 1-sun AM1.5 and indoor white light emitting diode (LED) light was compared. We find that the trends agree well with the detailed balance limit; however, the devices near the optimal bandgap (1.77 eV) perform worse due to the lower perovskite quality. Instead, we achieve the highest power conversion efficiency (PCE) of 34.0% under 870 lx with 1.67 eV and Al$_2$O$_3$ passivation. The perovskite with a bandgap of 1.71 eV is not far behind, with a high $V_{OC}$ of 1.02 V. Measurements under different white LED color temperatures confirm that the highest PCE is achieved under the warmest colors. All measurements were carried out in a dedicated indoor setup that ensures the diffuse light typical of indoor environments and allows both short- and long-term measurements. In the best case, we observe no degradation during the 33-day test under simulated office conditions with regular switching on and off of the light and a $T_{80}$ of 30 days under continuous illumination. The results were obtained from multiple batches, which corroborates our findings and gives them statistical relevance. photovoltaics perovskite solar cells indoor operation LED light sources detailed balance limit bandgap tuning stability diodes electrical conductivity power conversion efficiency solar cells fotovoltaika perovskitne sončne celice delovanje pod notranjimi pogoji LED viri svetlobe true false true Angleški jezik Slovenski jezik Članek v reviji 2024-11-18 12:31:12 2024-11-18 12:31:18 2025-01-07 03:48:18 0000-00-00 00:00:00 2024 0 0 Str. 62195-62202 iss. 45 Vol. 16 Nov. 2024 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 621.383.51:549.641 1944-8252 10.1021/acsami.4c14736 215382531 jost-et-al-2024-performance-of-triple-cation-perovskite-solar-cells-under-different-indoor-operating-conditions.pdf jost-et-al-2024-performance-of-triple-cation-perovskite-solar-cells-under-different-indoor-operating-conditions.pdf 1 8DB691C6418B002F56B973F334B6217B f8aecc760bbd30903a5fa00b2491cb836276799487aee569795c21eae6c6438a 48819bb2-cc33-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197807 https://pubs.acs.org/doi/10.1021/acsami.4c14736 1 3fd8b4ae-a5a0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=195794 Fakulteta za elektrotehniko 0 0 0
