Implication

This research examines how varying ammonia concentration affects the optical and electrical properties of CdS films, suggesting improvements for optoelectronic devices.

Key Points

  • Enhanced optical properties are achieved with increased ammonia concentration, resulting in a direct bandgap increase from 2.20 eV to 2.36 eV.
  • Optimization methods indicate better morphological uniformity and crystallinity with a 1:20 Cd2+/S2- molar ratio during synthesis.
  • Characterization of the Mo/CZTS/CdS/Ag diode confirms effective charge transport properties for the engineered CdS films.
  • Findings support the development of high-performance CdS-based solar cells, pushing advances in optoelectronic technologies.
