Randomized trial evaluates optical properties in Cu2FeSn3S8 thin films, suggesting efficiency for solar cells.

This study aims to synthesize and characterize Cu2FeSn3S8 thin films to assess their potential in photovoltaics.
Thin films prepared using pulsed laser deposition on soda-lime glass
Post-deposition annealing at 400°C for 1 hour in N2 atmosphere
Characterization via X-ray diffraction, Raman spectroscopy, and EDS compositional analysis
Post-deposition annealing converts amorphous films to partially crystalline thiospinel structure
Optical bandgap measured between 1.46-1.52 eV with enhanced optical absorption after annealing
Carrier mobility and photosensitivity are demonstrated, indicating suitable properties for solar absorbers

Jain et al. (2026) studied this question.
