Engineering Chemical Vapor Deposition for Lead-Free Perovskite-Inspired MA3Bi2I9 Self-Powered Photodetectors with High Performance and Stability

Van-Hoang Vuong et al.

Summary: Lead-free perovskite-inspired materials (PIMs) have shown promising electronic properties without the toxicity issues of lead-based perovskites, but have not matched the efficiency and stability of benchmark technologies in photodetectors. This study demonstrates the potential of high-performance self-powered photodetectors using a two-tube chemical vapor deposition (2T-CVD) approach to grow smoother and more compact photoactive films of methylammonium bismuth iodide (MA(3)Bi(2)I(9)). The results show that 2T-CVD offers a promising platform for the development of high-performance lead-free perovskite-inspired optoelectronics with improved efficiency and stability.

Self-Powered CsPbBr3 Perovskite Nanonet Photodetector with a Hollow Vertical Structure

Rui Wang et al.

Summary: By introducing perovskite nanonet photodetectors with a hollow vertical structure using a polystyrene microsphere template, the device not only allows easy entrance of light from the reticulated hollow surface but also reduces light reflection, resulting in improved device performance. The optimal CsPbBr3 perovskite photodetectors achieved high photoelectric performance with a switching ratio of up to 4.17 x 10(4), detectivity of 7.44 x 10(11) Jones, linear dynamic range of 108 dB, and rise/fall time of 0.1/0.16 ms.
