Multijunction solar cells promise a significant increase in the energy yield of photovoltaic (PV) systems thanks to their improved solar spectrum utilization compared with conventional single-junction cells. 1, 2, 3 The power conversion efficiency (PCE) of 2-terminal, monolithic perovskite/silicon tandems is now certified at 34.6% for a device area of 1 cm 2,
Stacking perovskite solar cells onto crystalline silicon bottom cells in a monolithic tandem configuration enables power-conversion efficiencies (PCEs) well above those of their single-junction counterparts. However, state-of-the-art wide-band-gap perovskite films suffer from phase stability issues. Here, we show how carbazole as an additive to the perovskite precursor

The project also included the development of a scalable perovskite-silicon tandem solar cell that achieved a 31.6% power conversion efficiency, first announced in September.
A number of major PV research and manufacturing companies worked together to identify ways to improve the cost effectiveness of monocrystalline silicon solar cells. The
The PCE of the hybrid BC silicon solar cell with an area of 158.75 × 158.75 mm 2 was tested with a mask aperture area of 209.8 cm 2. Finally, the PCE of the 1 cm 2 ST-PSCs was added to the PCE of the hybrid BC silicon solar cell under light filtering to obtain the PCE of the 4T tandem solar cell.
H.W. performed the measurement and analysis of residual strain. K.L. and X.Y. prepared the large-area perovskite filter sample. J.Z., J.H., and Q.Z. completed the preparation and certification of hybrid-BC silicon solar cells. All authors discussed the results and contributed to the revisions of the manuscript.
The hybrid BC silicon solar cell was obtained from Gold Stone (Fujian) Energy Company Limited and fabricated through the following process. First, the N-type monocrystalline silicon wafer (a) was double-sided polished in 20% KOH solution to remove the damage layer, and then cleaned using the RCA standard process.
The hybrid-BC silicon solar cell working under the transmitted light was tested and reached a third-party certified PCE of 12.71% (Supplementary Figs. 32 and 33). Therefore, we achieved four-terminal perovskite/silicon tandem solar cells with a record-certified efficiency of 33.10% (Fig. 4g and Table 1).
