Key Points

This research aims to explore how selenium composition affects the structural and optical properties of Cu2ZnSn(S1−xSex)4 thin films for photovoltaic applications.
Prepared thin films using pulsed laser deposition with selenium compositions x = 0.0–1.0.
Conducted x-ray diffraction to analyze crystallinity and phase formation.
Utilized atomic force microscopy to assess surface properties and roughness variation with composition.
Performed optical characterization using UV–Vis–NIR spectroscopy to determine absorption and band gap characteristics.
Films with low selenium content remained amorphous, while higher selenium led to polycrystalline formation.
Crystallite size increased from 12.3 to 17.9 nm with selenium composition reaching x = 1.0.
The absorption coefficient exceeded 10^4 cm−1 in the visible region, indicating strong light absorption.
The optical band gap varied between 2.00 and 2.30 eV, peaking at x = 0.6 due to quantum confinement.
Refractive index, extinction coefficient, and dielectric constants showed dependence on selenium content, reflecting optical response changes.
