In March 2024 — based on computer simulation — it was reported that 2-junction 1.5 eV CdTe/0.87 eV FeSi2 solar cells can achieve actual power conversion efficiency of 43.9 %, open circuit voltage of 1.928 V, and fill factor of 89.88 % at 300 K when the cells are irradiated by the air mass 1.5 global (AM1.5G) solar spectrum [M. H. Tonmoy et al., Heliyon 10 (2024) e27994]. These simulated values exceed the ideal detailed balance-limiting power conversion efficiency, open circuit voltage, and fill factor of a 1.5 eV/0.87 eV 2-junction solar cell.
