Key Findings in This Report

• CZTS-based heterojunction nanodevices were successfully fabricated for dual functionality as solar cells and self-powered photodetectors. • Rapid thermal processing (RTP) at 500 °C significantly improved crystallinity and surface morphology of CZTS films. • The photovoltaic device with 3-min CdS deposition achieved a power conversion efficiency of 1.15%, outperforming the 5-min counterpart (0.97%). • The fabricated devices exhibited self-powered photodetection capability, responding to wavelength-dependent light without external bias.
