Summary: After the rapid development of single-junction perovskite solar cells and organic solar cells, improving their power conversion efficiencies has become increasingly difficult. Tandem solar cells are gaining more attention due to their higher theoretical efficiency compared to single-junction solar cells. While good device performance has been achieved for perovskite/silicon and perovskite/perovskite tandem solar cells, very few studies have been done on 4-terminal inorganic perovskite/organic tandem solar cells. This work successfully fabricates 4-terminal inorganic perovskite/organic tandem solar cells using semi-transparent inorganic perovskite solar cells and organic solar cells, achieving higher efficiency than reported 2-terminal and 4-terminal inorganic perovskite/organic tandem solar cells.

Summary: In monolithic perovskite/silicon tandem solar cells, it is crucial to identify the limiting subcells for the overall current in order to optimize the perovskite absorber thickness and bandgap. A spectrometric characterization method is introduced to accurately determine the current matching point and analyze the behavior of individual subcells and their impact on tandem performance.

Summary: This study demonstrates a 2-terminal monolithic perovskite/organic tandem solar cell (TSC) configuration, which incorporates wide bandgap all-inorganic perovskites as front cell absorber and organic blend as rear cell absorber, to extend the absorption range of organic solar cells (OSCs) into high-energy photon region. By optimizing the electron transporting layer and interface structure, high open-circuit voltage and charge transport efficiency are achieved. The remarkable power conversion efficiency (PCE) obtained in this study highlights the potential of this strategy to improve the efficiency of OSCs.

Summary: This study presents a monolithic hybrid tandem solar cell with an all-organic blend as the rear subcell, using metal-ion doped all-inorganic perovskite front subcells and a solution-processed ternary organic blend rear subcell. The use of dynamic hot-air deposition technology allows the fabrication and testing of the solar cells entirely in the open air, and passivation and selection layer treatments improve efficiency and reduce open-circuit voltage loss. The solar cells achieved a maximum efficiency of 23.07% and retained over 90% of the initial efficiency after 600 hours of continuous illumination.

Summary: By incorporating Cl and conducting surface treatment for the CsFAPb(IBr)(3) system, this study successfully reduced defect densities and significantly improved open-circuit voltage and power conversion efficiency in PSCs. Integration of a highly efficient 1.67 eV PSC top cell with various bandgap CIGS solar cells resulted in a calculated tandem efficiency of 28.4%, currently the highest for PSC/CIGS tandem cells. The findings pave the way for highly efficient monolithic two-terminal PSC/CIGS tandem devices in the future.

Summary: The power conversion efficiency (PCE) of polymer solar cells (PSCs) has reached >19% through the development of non-fullerene acceptors. Interfacial layers (ILs) play a crucial role in improving charge extraction. In this study, different alkali metal cations (Li+, Na+, and K+) in ionic iridium(iii) (Ir(iii)) complexes were used to enhance charge collection efficiency between zinc oxide and active layers. The introduction of an IL (Ir-K+) increased the PCE of PM6:Y6-based PSCs from 14.0% to 15.6%. Moreover, the stability of PSCs containing ionic Ir(iii) complexes was significantly enhanced under UV light and one-sun irradiation.
