“…The antireflection layer will enhance the light absorption of perovskite top cell while the rear‐side texture will enhance the light absorption of the Si bottom cell. The final 2T tandem device shows a PCE of 21.6% with a high V oc of 1.837 V, a J sc around 15.2 mA/cm 2 and a FF of 75.3% 81–83 . In this work, the overall current of the tandem cell is still limited by the perovskite top cell even it has a front antireflection layer which can effectively enhance the current of top cell.…”

“…From the SEM image, it can be seen that the top C 60 /SnO 2 layer in p‐i‐n structure is much thinner than spiro‐OMeTAD in n–i–p structure, which is better for device light absorption. However, it is still hard to conclude which structure of perovskite top cell is better for 2T tandem device since both structures have been widely studied and decent efficiency have been achieved 46,50,81–83 …”

“…However, it is still hard to conclude which structure of perovskite top cell is better for 2T tandem device since both structures have been widely studied and decent efficiency have been achieved. 46,50,[81][82][83] Different from the 2T configuration, a 4T tandem device only requires optical coupling between the subcells. Therefore, the perovskite cell and Si cell are fabricated separately and then put together to form a 4T tandem device.…”

The world record device efficiency of single‐junction solar cells based on organic–inorganic hybrid perovskites has reached 25.5%. Further improvement in device power conversion efficiency (PCE) can be achieved by either optimizing perovskite films or designing novel device structures such as perovskite/Si tandem solar cells. With the marriage of perovskite and Si solar cells, a tandem device configuration is able to achieve a PCE exceeding the Shockley–Queisser limit of single‐junction solar cells by enhancing the usage of solar spectrum. After several years of development, the highest PCE of the perovskite/Si tandem cell has reached 29.5%, which is higher than that of perovskite‐ and Si‐based single‐junction cells. Here, in this review, we will (1) first discuss the device structure and fundamental working principle of both two‐terminal (2T) and four‐terminal (4T) perovskite/Si tandem solar cells; (2) second, provide a brief overview of the advances of perovskite/Si tandem solar cells regarding the development of interconnection layer, perovskite active layer, tandem device structure, and light management strategies; (3) third, discuss the challenges and opportunities for further developing perovskite/Si tandem solar cells. This review article, on the one hand, provides a comprehensive understanding to readers on the development of perovskite/Si tandems. On the other hand, it proposes various novel applications that may bring such tandems into the market in a near future.

Tandem solar cells (TSCs) comprising stacked narrow‐bandgap and wide‐bandgap subcells are regarded as the most promising approach to break the Shockley–Queisser limit of single‐junction solar cells. As the game‐changer in the photovoltaic community, organic–inorganic hybrid perovskites became the front‐runner candidate for mating with other efficient photovoltaic technologies in the tandem configuration for higher power conversion efficiency, by virtue of their tunable and complementary bandgaps, excellent photoelectric properties, and solution processability. In this review, a perspective that critically dilates the progress of perovskite material selection and device design for perovskite‐based TSCs, including perovskite/silicon, perovskite/copper indium gallium selenide, perovskite/perovskite, perovskite/CdTe, and perovskite/GaAs are presented. Besides, all‐inorganic perovskite CsPbI3 with high thermal stability is proposed as the top subcell in TSCs due to its suitable bandgap of ≈1.73 eV and rapidly increasing efficiency. To minimize the optical and electrical losses for high‐efficiency TSCs, the optimization of transparent electrodes, recombination layers, and the current‐matching principles are highlighted. Through big data analysis, wide‐bandgap perovskite solar cells with high open‐circuit voltage (Voc) are in dire need in further study. In the end, opportunities and challenges to realize the commercialization of TSCs, including long‐term stability, area upscaling, and mitigation of toxicity, are also envisioned.
