Inhibited Crack Development by Compressive Strain in Perovskite Solar Cells with Improved Mechanical Stability

Guizhou Yuan et al.

Summary: This study investigates the formation and evolution of cracks in perovskite films during thermal cycling, which affect their mechanical stability. The use of compressive strain and in situ formed polymers with low elastic modulus suppresses cracks and delamination, resulting in mechanically stable devices. The perovskite solar cells achieved a power conversion efficiency of 23.91% (0.0805 cm(2)) and 23.27% (1 cm(2)) in p-i-n structure, and retained 95% of the initial efficiency after 230 cycles. These findings provide new insights into strain engineering for stable perovskite solar cells.

Controlled crystal orientation of two-dimensional Ruddlesden-Popper halide perovskite films for solar cells

Jiuyao Du et al.

Summary: Metal halide perovskite solar cells are attractive due to their high efficiency and low cost, but they lack structural stability. Two-dimensional Ruddlesden-Popper perovskites provide a solution with their excellent stability and controlled crystallographic orientation. However, controlling the crystallographic orientation of 2D RP perovskites prepared by solution process is difficult.

Plasmonic Local Heating Induced Strain Modulation for Enhanced Efficiency and Stability of Perovskite Solar Cells

Fengzhu Li et al.

Summary: The efficiency and stability of perovskite solar cells (PVSCs) are significantly affected by the residual strain induced during the growth of the perovskite film. In this study, SiO2-coated gold nanorods (GNR@SiO2) were introduced into the perovskite film to release the strain using the plasmonic local heating effect. The resulting inverted PVSCs with GNR@SiO2 exhibited a champion power conversion efficiency (PCE) over 23% and improved stability, retaining 84% of its initial PCE after aging for 2800 hours under continuous illumination at 65 +/- 5 degrees C.
