All-perovskite tandem solar cells with improved grain surface passivation

Renxing Lin et al.

Summary: Researchers have developed ammonium-cation-passivated Pb-Sn perovskites with long diffusion lengths, enabling high-efficiency all-perovskite tandem solar cells. By enhancing the adsorption of the passivator using a stronger surface-passivator interaction, the carrier diffusion length within Pb-Sn perovskites is doubled, resulting in an efficiency of over 22%. The certified efficiency of 26.4% achieved in the all-perovskite tandem solar cells exceeds that of the best-performing single-junction perovskite solar cells.

Interface Engineering in Solution-Processed Thin-Film Solar Cells

Fengzhu Li et al.

Summary: With the rapid industrialization, the demand for clean and renewable energy sources has been increasing. Photovoltaics (PV) has shown great potential in directly converting sunlight into electricity. Solution-processed thin-film solar cells, such as organic solar cells (OSCs) and organic-inorganic hybrid perovskite solar cells (PVSCs), have unique advantages over conventional PVs based on crystalline silicon. The design of interfaces plays a vital role in achieving high power conversion efficiency (PCE) and stability in PV devices. This Account provides an introduction to the fundamental roles of interfaces in PVs and discusses detailed analysis of interfaces and related surface science. Various interfacial materials with different functionalities are also highlighted, along with the challenges and future perspectives for the commercialization of solution-processed thin-film PVs.

Perovskite solar cells with atomically coherent interlayers on SnO2 electrodes

Hanul Min et al.

Summary: By introducing an interlayer between the electron-transporting and perovskite layers in perovskite solar cells, researchers have successfully enhanced charge extraction and transport from the perovskite, leading to higher power conversion efficiency and fewer interfacial defects. The coherent interlayer allowed the fabrication of devices with a certified efficiency of 25.5%, which maintained about 90% of its initial efficiency even after continuous light exposure for 500 hours. The findings provide guidelines for designing defect-minimizing interfaces in metal halide perovskites and electron-transporting layers.
