Abstract

This study develops an environmentally sustainable, lead-free Cs 2 SnCl 6 double perovskite for Schottky photodetectors, enhanced with multiwalled carbon nanotubes (MWCNTs) to improve charge transport and optoelectronic performance. Comprehensive characterization confirms that MWCNTs enhance conductivity and reduce trap energy from 103.22 to 79.70 meV in the dark. MWCNT-incorporated devices exhibit improved responsivity (2.57 mA/W) and detectivity (2.38 × 10 9 Jones) under UV illumination at 350 nm. Additionally, a microcontroller-integrated UV detector interfacing with a smartphone demonstrates practical application. This work underscores the role of MWCNTs in advancing lead-free, stable, perovskite-based UV photodetectors.
