摘要/Abstract：
Solar cells play a vital role in transforming energy needs. Single-junction solar cells made of metal halide perovskite materials have shown great potential, achieving about 26% efficiency in converting sunlight into electricity (1). This makes them attractive for photoelectronic applications, such as lasers, light detectors, and light-emitting diodes. Breaking this efficiency limit of single-junction solar cells could be achieved with tandem solar cells, where thermalization loss is reduced and solar spectrum utilization range is broadened (2). Small-area all-perovskite tandem cells can reach an efficiency of >28% (3). However, developing large-area (∼20 cm2) allperovskite tandem modules is challenging because of difficulties in controlling homogeneous crystallization when scaling up perovskites. On page 855 of this issue, Gao et al. (4) report large-area all-perovskite tandem modules that achieve >24% efficiency. The approach may offer a viable route for commercialization.
