20.500.12556/RUL-140519 Perovskite/CIGS tandem solar cells from certified 24.2% toward 30% and beyond We demonstrate a monolithic perovskite/CIGS tandem solar cell with a certified power conversion efficiency (PCE) of 24.2%. The tandem solar cell still exhibits photocurrent mismatch between the subcells; thus optical simulations are used to determine the optimal device stack. Results reveal a high optical potential with the optimized device reaching a short-circuit current density of 19.9 mA cm$^{−2}$ and 32% PCE based on semiempirical material properties. To evaluate its energy yield, we first determine the CIGS temperature coefficient, which is at −0.38% K$^{−1}$ notably higher than the one from the perovskite subcell (−0.22% K$^{−1}$), favoring perovskite in the field operation at elevated cell temperatures. Both single-junction cells, however, are significantly outperformed by the combined tandem device. The enhancement in energy output is more than 50% in the case of CIGS single-junction device. The results demonstrate the high potential of perovskite/CIGS tandem solar cells, for which we describe optical guidelines toward 30% PCE. photovoltaics perovskite tandem solar cells optical optimization energy yield electrical conductivity layers perovskites power conversion efficiency solar cells fotovoltaika perovskitne tandemske sončne celice optična optimizacija energijski izplen true false true Angleški jezik Slovenski jezik Članek v reviji 2022-09-15 10:06:23 2022-09-15 10:06:24 2022-09-24 04:12:16 0000-00-00 00:00:00 2022 0 0 Str. 1298-1307 iss. 4 Vol. 7 Apr. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.383.51 2380-8195 10.1021/acsenergylett.2c00274 100592131 acsenergylett.2c00274_PerovskiteCIGS_tandem_solar_cells.pdf acsenergylett.2c00274_PerovskiteCIGS_tandem_solar_cells.pdf 1 701D13959D4F2D2EB48C0032BBA2BC17 fb12389540fc474583320e03512ec520224cfad0e83474bd566e726ded30f941 fa0c3d24-3b1f-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=162043 https://pubs.acs.org/doi/10.1021/acsenergylett.2c00274 1 39b4f90b-34cd-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=161265 Fakulteta za elektrotehniko 0 0 0
