Summary: This paper presents the fabrication of large-area four-terminal perovskite-Si solar cells and discusses their efficiencies. Large-area semi-transparent perovskite solar cells were fabricated using a thin copper layer as a transparent electrode, and a carrier selective contact-based Si solar cell was also fabricated. The efficiencies of these cells and a commercially available monocrystalline-Si solar cell were evaluated under different illumination conditions, and the combined efficiencies of the 4 T configurations were calculated.

Summary: This study investigates the enhanced optical absorption of a ternary chalcogenide semiconductor through engineering cation disorder, which enables the development of highly efficient extremely thin absorber photovoltaic devices. The experimental results demonstrate that colloidal nanocrystals with engineered cation disorder show a significantly higher absorption coefficient compared to other photovoltaic materials, offering a promising solution for environmentally friendly and solution-processed solar cells.

Summary: Perovskite/organic tandem solar cells have a promising future in thin-film photovoltaics due to the large chemical composition and tunability of their bandgap. However, their efficiency is currently limited by the open-circuit voltage loss and non-ideal interconnecting layers. In this study, the passivation of nickel oxide hole-transporting layers and the development of an optimized interconnecting layer structure led to a significant increase in efficiency, reaching a maximum of 23.60% (22.95% certified) in perovskite/organic tandem solar cells.

Summary: This study reveals the exciton dynamics in quantum dot solids using transient absorption microscopy and observes the changes and transitions in initial exciton diffusion. The spacing between quantum dots, packing density, and heterogeneity all have an impact on exciton dynamics. These findings contribute to the control of optoelectronic properties in quantum dot solids.

Summary: A new secondary deposition approach was developed to increase quantum dot (QD) loading and enhance the performance of QD sensitized solar cells (QDSCs) without introducing new recombination centers. By creating a metal oxyhydroxide layer around QD presensitized photoanodes, the photovoltage, fill factor, and efficiency of the ZCISSe QDSCs were remarkably improved. This innovative method achieved a new certified power conversion efficiency (PCE) record of 15.20% for liquid-junction QDSCs.
