MWCNT-Enhanced Cs2SnCl6 Perovskite for Improved Charge Transport in a Smartphone-Interfaced UV Photodetector
This study develops an environmentally sustainable, lead-free Cs2SnCl6 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 × 109 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.
期刊介绍：
ACS Applied Electronic Materials is an interdisciplinary journal publishing original research covering all aspects of electronic materials.
