Lead-Free CsBi3I10 Thin-Film flexible photodetectors with enhanced performance for broad spectral response
By employing a hot spin-coating method, CsBi3I10 thin-film photodetector was fabricated onto flexible PET substrate. The resulting nontoxic photodetector demonstrated exceptional optoelectronic performance, featuring an Ilight/Idark ratio of 1.8 × 103, a responsivity of 18.3 mA/W and a detectivity of 2.95 × 108 Jones. It also showed a broad spectral response and maintained consistent performance after 506 light switching cycles and 1000 bending cycles. The dynamic imaging capability of the device was further validated, illustrating its potential for diverse applications. This work pioneers the application of CsBi3I10 perovskite thin-film in flexible photodetectors, offering a green, stable and high-performance solution for next-generation optoelectronic devices.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
