The development of biodegradable mulch for agricultural applications represents a sustainable approach to reducing plastic pollution. Poly(vinyl alcohol) (PVA) is one of the nontoxic and biodegradable polymers that can be used as mulching film. However, a major drawback of PVA is its moisture sensitivity, which limits its applications. In this study, a biocomposite based on PVA and polyhydroxybutyrate (PHB), plasticized with triacetin, was developed by solvent casting method. The biocomposite film exhibited good mechanical properties, better integrity, reduced transmittance, and light-blocking properties, which can prevent weed growth. Additionally, an improvement in surface characteristics was observed, as demonstrated by the shift in contact angle from 44 to 99°and a reduction in the water vapor transmission rate (WVTR) from 4.82 to 2.31 g/h m 2 . For agronomic application, the developed films were experimentally applied as mulch for maize plants in pots. The results were positive, showing that the mulches effectively supported the growth of the maize plants. Further, signs of initial degradation were observed after 5 days, and the film reached a degradation level of 50−55% after 30 days under natural conditions. Thus, this work has provided new insights for expanding the application range of PVA films in biobased mulching materials.

Lead‐free ternary bismuth halide perovskites A3Bi2X9 have gained much attention as a solution for toxic and unstable lead halide perovskites due to their facile solution processability, high optical absorption coefficient, and high stability. However, their photovoltaic performance remains poor due to their wide bandgap (∼2 eV), and poor charge transport properties stem from their low‐dimensional crystal structure. To promote the 3D structure and reduce the bandgap of ternary Bi‐halide perovskites, we replace the alkali elements at the A‐site with the transition element Ag+ to obtain a new class of perovskite‐like materials named rudorffites AgaBibIa+3b. We investigated the photophysical properties of AgBiI4 by a combined theoretical and experimental approach. Our DFT‐PBE‐SOC predicted band gap for cubic defect spinel AgBiI4 is 2.01 eV, while that obtained for spin‐coated AgBiI4 film is 1.67 eV. Furthermore, the strong p‐p band edge transition leads to high optical absorption in this material. Finally, a photodetector device fabricated using AgBiI4 shows excellent photoresponsivity (183 μA/W) and detectivity (20.93×108 Jones) with a fast rise/decay time of 0.27 s/0.29 s. This newly explored semiconductor class can be a promising and stable choice for advanced optoelectronic devices.
