Flexible perovskite solar cells (f‐PSCs) have drawn widespread interest owing to their distinguished advantages in excellent flexibility and relatively low cost. However, the brittle grain boundaries (GBs) and defects in flexible perovskite film tremendously influence the power conversion efficiency (PCE) and mechanical flexibility of f‐PSCs. Herein, photothermal welding, a novel method, is used to improve the perovskite films quality and the PCE of f‐PSCs with a near‐infrared (NIR) dye (indocyanine green, ICG) and polycaprolactone (PCL) as additives. Due to the strong photothermal effect, ICG molecule not only can significantly enhance NIR light harvesting, but it also can weld GBs upon exposure to an NIR laser, which is conducive to the GBs connections and device flexibility. Meanwhile, the S═O bond of ICG and C═O bond of PCL can simultaneously coordinate with Pb2+ defects in perovskite. Furthermore, they can control crystal growth to form a smooth surface of perovskite film. Consequently, the unencapsulated PSCs based on ICG/PCL displays a high champion PCE of 20.62%, with 88.4% of the original PCE after being placed in dark conditions for 600 h. The f‐PSCs delivers a champion PCE of 19.55% and exhibits excellent mechanical stability, thus providing a meaningful scientific direction to fabricate high‐flexible f‐PSCs.

Chalcogenide perovskites are emerging as a promising alternative to hybrid halide perovskites for optoelectronic applications, owing to their excellent light absorption and chemical stability. This study investigates the performance of single‐ and dual‐absorber solar cell devices using InBiSe3 and GaBiSe3 as absorber materials, simulated using the solar cell capacitance simulator in one dimension software. The devices employ WS2 as the electron transport layer and CuO as the hole transport layer. For single‐absorber devices, GaBiSe3 achieve a power conversion efficiency (PCE) of 26.58%, with a VOC of 0.94 V, a fill factor (FF) of 86.82%, and a short‐circuit current density (JSC) of 32.52 mA cm−2. InBiSe3 performs slightly lower, with a PCE of 21.44%, VOC of 1.25 V, FF of 87.83%, and JSC of 19.49 mA cm−2. The bilayer configuration, incorporating InBiSe3 as the top layer and GaBiSe3 as the bottom layer, shows the highest efficiency of 30%, with a VOC of 1.06 V, JSC of 32.78 mA cm−2, and FF of 85.97%. The study also examines the effects of temperature, shunt resistance, and series resistance on the device performance, as well as the influence of absorber layer thickness, defect density, and back contact variations.
